A worn, rusted, or chipped cooking grate quietly sabotages every backyard cookout. Hot spots flare up, smaller food slips through the bars, and that clean sear mark becomes a distant memory. Replacing the grate is often the cheapest way to feel like you’ve got a new grill again, and matching the right replacement to your model is the part most people stall on.

A Deeper Look At The Lineup
Nexgrill owners running a Home Depot 4-burner know how fast porcelain wears off a stock grate, and this Uniflasy pair aims straight at that headache. Built from stainless steel rods with notably tight spacing, the set drops in as a direct fit for the 720-0830H and a long list of sibling Nexgrill model numbers. For a backyard cook who flips a lot of vegetables or small seafood, those narrow gaps keep food from vanishing into the firebox.
Compared to the heavier cast-iron grates Uniflasy also sells for the same Nexgrill line, this stainless set trades a bit of heat retention for easier cleanup. Most owners find a stiff brush and a warm soak handles residue without the seasoning routine cast iron demands. For someone who’d rather scrape and go than oil and store, that tradeoff reads as a clear win.
Positive Takeaways
- Tight rod spacing prevents small food from dropping into the burner area
- Stainless surface resists rust under typical backyard conditions
- Direct fit for the 720-0830H and multiple Nexgrill variants
- Lighter than cast iron, simpler to lift during cleaning
- Smooth surface wipes down without heavy scrubbing
Points To Keep In Mind
- Stainless won’t hold sear marks as aggressively as cast iron
- Compatibility list is long; double-check your specific model number before ordering
Who It Suits Best
Backyard cooks with a Home Depot Nexgrill 4-burner who want a low-maintenance stainless swap.
Look Elsewhere When
If you own a Weber Spirit, the Uniflasy 7639 Grill Grates for Weber Spirit 300 & GS4 Spirit II 300 is the better-matched fit for that grill family.
Weber Spirit owners have a confusing decade spread of model numbers to track, and that’s exactly where this grate earns its keep. It lines up with the Spirit 300 series, the Spirit II E-310 and family, the Spirit 700, and the Genesis Silver, Gold, and Platinum B/C trims from 2005, plus Genesis 1000 through 3500. For someone with an older grill buried in the garage, that kind of cross-generation coverage removes the usual guessing game.
Unlike the single-model fit of pick 1’s Nexgrill grates, this stainless set covers both front- and side-mounted control panel Spirit variants, which is the detail most aftermarket listings quietly skip. Front-control E310s and side-control S310s sit at slightly different offsets, and getting that right means the grate actually seats flush.
The Good Stuff
- Covers both front- and side-control Weber Spirit layouts
- Replaces Weber part 7639 across many generations
- Stainless steel construction for easier day-to-day cleaning
- Lighter weight than the cast-iron 7638 it parallels
Trade Offs
- Stainless loses heat faster than cast iron between flare-ups
- Model list is long; you still need to confirm your specific Spirit or Genesis variant before clicking order
- Doesn’t include flavorizer bars or burner tubes, unlike the full Spirit kit below
Key Specs
Made For
Spirit and Genesis owners with a 7639-style stainless grate who want a confirmed cross-generation replacement.
Consider Something Else When
If your Spirit also needs new burner tubes and flavorizer bars, the Uniflasy Grill Parts for Weber Spirit E310 kit bundles all three instead of just the grates.
Sitting right next to pick 2, this Uniflasy 7639 listing is the simpler, more focused answer for Spirit owners who don’t need Genesis coverage. It targets the Spirit 300 line, the Spirit II GS4 300 series, the Spirit 700, the Genesis B/C trims from 2005, and Genesis 1000 through 3500, framing itself as a direct 7639 stainless replacement. If you want a clean match without wading through extra model numbers, the narrower scope helps.
The honest read is that pick 2 and this one cover very similar ground, with the difference showing up in how each listing groups compatible models. Most backyard cooks who already know their Spirit sub-model won’t notice the overlap, and either pick will drop in cleanly on an E310 or S310.
Reasons It Performs
- Direct 7639 stainless replacement, no guesswork on fit
- Covers Spirit 300, Spirit II GS4 300, Spirit 700, and Genesis 1000-3500
- Handles both front- and side-control Spirit layouts
- Easier to lift and scrub than a cast-iron equivalent
Less Ideal Details
- Doesn’t include flavorizer bars or burner tubes, so a full Spirit refresh needs the bundled kit below
- Stainless steel loses heat between batches faster than cast iron
Right Fit For
Spirit 300 or Spirit II 300 owners who just need the cooking grates and nothing else.
Not Your Match When
If your Genesis is part of an outdoor kitchen setup, the QuliMetal 18.75″ Grill Grates for Weber Genesis II & II LX 300 Series is built specifically for that newer platform.
Charbroil’s model number system punishes casual shoppers, and that’s why a single, well-measured replacement grate has real value. This S5421A grid is sized at 16 3/8 by 21 1/2 inches and fits the Charbroil 463722313, 463722314, 463742111, and 463722315 grills. You get one grate in the box, so it’s best for replacing a single worn section rather than a full set.
The honest read is that a stainless wire grid cleans fast, but it doesn’t insulate heat the way porcelain-coated steel does, so you may notice slightly cooler recovery between batches on a cold grill. For casual weeknight cooks that barely register, but for high-heat steak sears it can matter.
Everyday Wins
- Compact 16 3/8 by 21 1/2 inch footprint fits several popular Charbroil 463-series grills
- Stainless steel wire construction wipes clean without scrubbing
- Single-pack pricing helps when only one grate has rusted through
Honest Caveats
- One grate per order; a full-cooktop refresh needs multiple purchases
- Stainless wire cools faster than porcelain-coated steel, which can affect high-heat searing
- Doesn’t list wider Charbroil series coverage beyond the 463 models named

Skip It When
For a Home Depot Nexgrill 4-burner refresh, the Uniflasy 17.25″ Stainless Steel Grill Grates for Nexgrill 720-0830H covers a wider area in one set.
Home Depot’s Nexgrill models are a separate SKU family from the direct-buy Nexgrill line, and that’s where this two-pack slots in. Each grate measures 17 by 13.2 inches, with a 7mm bar thickness, giving you two grates that together cover a 17 by 26.4 inch area. The fit list pulls in the 720-0830H, 720-0830D, 720-0783E, 720-0783C, and the 5-burner 720-0888 family.
Compared to pick 1, this set ships with more rods than the typical OEM layout, and the tighter spacing is the headline feature. Small food items stop falling through, and the denser bar pattern means more even contact for thinner cuts of meat or fish. The 7mm thickness gives the grates enough body to resist flexing when you slide a heavy roast around.
Useful Highlights
- Higher rod count than OEM for better support of small foods
- Two-pack covers a full 4-burner cooktop in one order
- 7mm bar thickness resists flexing under heavy roasts
- Fits both 4- and 5-burner Home Depot Nexgrill models
- Stainless surface cleans with a brush and minimal effort
Things To Weigh
- Tighter rod spacing can slow grease drainage, so drip management matters
- Verify your exact Nexgrill model number before ordering; the Home Depot and direct-buy lines are different
Who Should Grab It
Home Depot Nexgrill 4- or 5-burner owners who want denser rod spacing than the original factory grate.
Another Choice May Suit
If you own a Weber Spirit instead, the Uniflasy 7639 Grill Grates for Weber Spirit 300 & GS4 Spirit II 300 matches that platform more precisely.
When a Spirit starts running cold in spots or the flame pattern looks ragged, the fix usually isn’t just the grates. This kit pairs 17.5-inch cast-iron cooking grates with 304 stainless steel burner tubes (the 69787 part) and porcelain-coated steel flavorizer bars (the 7636 part). One order covers the three wear items most likely to be aging at the same time on a five-year-old grill.
Unlike picks 2 and 3, which are grates only, this set is a system rebuild. If your Spirit is rusting through in multiple places, piecing it together part by part costs more and risks mixing up model-specific pieces. The cast-iron grates here also bring back the heavier sear marks that stainless tends to soften.
What Earns Its Place
- Three core wear items in one kit: grates, burner tubes, flavorizer bars
- Cast-iron grates bring back strong sear marks
- 304 stainless burner tubes resist corrosion over repeat heating cycles
- One purchase replaces parts that typically age together on older grills
Practical Considerations
- Cast-iron grates require seasoning and more careful cleaning than stainless
- Heavier set overall, so installation is a two-hand job
- More expensive than grates alone, which is overkill for grills that only need the cooking surface
Technical Sheet
Built With In Mind
Spirit owners with an aging grill who need grates plus burner tubes plus flavorizer bars replaced at the same time.
Swap It Out When
If your grill only has surface rust on the grates and the burners still light evenly, the Uniflasy 7639 Grill Grates for Weber Spirit 300 & GS4 Spirit II 300 is a more focused, lower-cost fix.
The Genesis II 300 lineup introduced a different cooking chamber footprint than the older Spirit 300 platform, and QuliMetal built these 18.75-inch grates specifically for that newer shape. They replace Weber parts 66095 and 66802 across the E-310, S-310, E-315, E-325, E-330, SE-330, CE-330, S-335, SE-335, E-335, and S-345 models from 2017 onward. If you own a Genesis II with the GS4 grilling system, this is the drop-in part.
Compared to the older Genesis 1000-3500 coverage that picks 2 and 3 list, this QuliMetal set skips the legacy trims entirely and focuses only on the post-2017 Genesis II family. For someone with a 2018 or newer Genesis II 300, that focus translates to fewer model-number cross-checks and a tighter fit guarantee.
Useful Touches
- Sized at 18.75 inches for the Genesis II 300 cooking chamber
- Replaces Weber parts 66095 and 66802 directly
- Covers 2017 and newer Genesis II E, S, SE, and CE sub-models
Where It Is Less Suited
- Doesn’t fit pre-2017 Genesis or Spirit 300 grills
- Grates only; burner tubes and flavorizer bars aren’t included
Perfect Match For
Genesis II 300 owners with 2017-and-newer builds who want a focused replacement rather than a cross-generation list.
Reach For A Different Pick When
For an older Spirit 300 or pre-2017 Genesis, the Uniflasy Grill Grates for Weber Spirit 300 & Spirit II GS4 300 Series covers that older platform.
Dyna-Glo’s 3-burner open-cart grills are common at big-box stores, and the DGC310CNP-D, DGC310RNP-D, and DGC310BNP-D variants all share the same cooking chamber. Hisencn’s porcelain-coated steel grate measures 19 3/5 by 15 2/5 inches and fits that exact family, so a single purchase handles one worn grate on a mid-size propane grill. The porcelain finish gives it a smoother nonstick feel than bare steel.
Unlike the stainless steel grates that dominate picks 1 through 7, porcelain-coated steel brings back some heat retention while keeping cleanup light. Most owners find food release is a touch easier than on a raw stainless wire grid. The honest read is that the porcelain can chip if you scrape too aggressively, so a softer brush tends to last longer.
A Strong Showing
- Porcelain coating helps food release and resists sticking
- Direct fit for the DGC310CNP-D, DGC310RNP-D, and DGC310BNP-D models
- 19 3/5 by 15 2/5 inch footprint matches the 3-burner cooking chamber
A Few Limitations
- One grate per order, so a full cooktop needs more than one purchase
- Porcelain can chip under aggressive metal scraping
- Not compatible with Dyna-Glo 4- or 5-burner models
Whose Shelf It Belongs On
Dyna-Glo 3-burner DGC310 owners who want a porcelain-coated surface without buying a full grate set.
Where A Sibling Pick Shines
For a Weber Genesis II owner, the QuliMetal 18.75″ Grill Grates for Weber Genesis II & II LX 300 Series is the cleaner fit for that platform.
Bull outdoor kitchens are a different category from backyard gas grills, and the warming rack here is built to slot into the brand’s 30-inch models. It’s listed for the Angus, Outlaw, Bison, Lonestar, and 7-burner Bull grills, with three dimension variants offered depending on the series: 21.6 by 9.5, 24.9 by 4.7, and 25 3/4 by 12 inches. Pick the right size before you order because the rack is not interchangeable across those dimensions.
Unlike the main cooking grates in picks 1 through 8, this is a warming rack, the upper-level shelf that holds finished food or toasts buns while the main grate handles the entrée. For Bull owners whose original rack has rusted or bent, this restores that second tier without replacing the entire grill.
What Pays Off
- Direct fit for Bull Angus, Outlaw, Bison, Lonestar, and 7-burner 30″ models
- Restores a useful second-tier surface for resting and toasting
- Stainless steel construction for outdoor kitchen durability
Points To Note
- Not the main cooking grate; the primary rack is a separate part
- Three dimension variants exist; verifying your model’s size before ordering matters
- Specific to Bull 30-inch grills, so it won’t cross over to other brands
Who Will Love This
Bull 30-inch outdoor kitchen owners whose warming rack has rusted or bent and needs a direct-shape replacement.
A Better Fit Elsewhere
For a standard backyard gas grill, the S5421A Stainless Steel Cooking Grid for Charbroil Models handles a much broader range of mainstream models.
Americana’s 3000-4000 series grills are a value-tier line that doesn’t always get aftermarket love, so a dedicated replacement grid is a quiet win. This HENSITA grate matches OEM part 1025.8.001 at 19.25 by 18.5 inches, and the steel wire construction is built for repeated high-heat sessions. The straightforward drop-in fit means no trimming or bending to make it seat.
The honest read is that a steel wire grid, not porcelain-coated, will eventually show surface rust in coastal or humid climates. For most backyards with normal weather exposure, that’s a multi-season concern rather than an immediate one. For a budget-friendly swap that gets an older Americana back into regular rotation, it does the job.
What Works In Its Favor
- Direct match for Americana OEM part 1025.8.001
- 19.25 by 18.5 inch footprint fits without modification
- Steel wire construction handles repeated high-heat grilling
- One-piece grid simplifies the swap for a single worn rack
Where It May Fall Short
- Bare steel can show surface rust sooner than porcelain-coated or stainless alternatives in humid climates
- Doesn’t list compatibility outside the Americana 3000-4000 series

Wrong Turns To Avoid
For a Weber Spirit instead, the Uniflasy 7639 Grill Grates for Weber Spirit 300 & GS4 Spirit II 300 lines up with that model family.
Factors To Weigh Before Choosing Bbq Grill Replacement Racks
Match The Model Number First
Every grill brand prints a model number on a sticker somewhere on the frame, often on the back panel or inside the cabinet door. Cross-checking that number against the replacement listing’s compatibility list is the single most reliable way to avoid a return. Models that share a series name but differ by one letter often use different grate dimensions, so the sticker beats the marketing copy every time.
Material Shapes The Cooking Feel
Stainless steel grates heat up fast and wipe clean easily, but they don’t retain heat as aggressively between batches. Cast iron holds heat longer and produces sharper sear marks, but it demands seasoning and more careful drying to prevent rust. Porcelain-coated steel sits in between, with smoother food release and a finish that can chip if you scrape too hard. For weeknight cooks who prioritize easy cleanup, stainless tends to win; for steak night purists, cast iron earns its extra care.
Rod Spacing And Bar Thickness
Tighter rod spacing keeps small food from falling through, which matters most for vegetables, shrimp, and flaky fish. A bar thickness of around 7mm resists flexing when you slide a heavy roast across the surface. Wider spacing lets grease drain faster but sacrifices small-food support. Picking the right balance depends on what you actually grill most weekends.
One Grate Or A Full Refresh
A single grate works when only one section has rusted through, and it costs less upfront. A bundled kit that includes burner tubes and flavorizer bars costs more but rebuilds the cooking system at once, which is the right call when a grill is aging in multiple places at the same time. Matching the scope of the replacement to the actual wear pattern keeps the project efficient.
Key Things To Know Before You Order
Where Shoppers Go Wrong
The most common mistake is trusting the series name alone instead of the specific model number. Spirit 300 and Spirit II 300 sound interchangeable but use different grate dimensions, and a grate built for one will rock loosely on the other. Measuring the existing grate from edge to edge, including any curved corners, catches that mismatch before you order. Skipping that step is how most returns happen.
When Paying More Pays Off
A bundled kit like the Uniflasy Grill Parts for Weber Spirit E310 Replacement Set costs more than a single grate, but it replaces grates, burner tubes, and flavorizer bars together. When those parts are all aging at the same rate, buying the kit costs less than three separate purchases and avoids the risk of mismatched parts. The premium is worth it during a full refresh, not when only one component has worn out.
Frequently Asked Questions
How Do I Know Which Bbq Grill Replacement Rack Fits My Grill?
Look for the model number on a sticker, usually on the back of the grill or inside the cabinet door, and match it against the listing’s compatibility list. Measure your existing grate edge to edge if you want extra confidence before ordering.
Are Stainless Steel Grates Better Than Cast Iron?
Stainless steel heats up faster and cleans with less effort, while cast iron holds heat longer and produces sharper sear marks but needs seasoning. The right choice depends on whether you prioritize convenience or maximum sear performance.
Can I Replace Just One Grate Instead Of The Whole Set?
Yes, single-pack options like the S5421A Stainless Steel Cooking Grid for Charbroil Models let you swap one section at a time. Just confirm the dimensions match your existing grate so the replacement seats properly.
How Tight Should The Rod Spacing Be?
Tighter spacing prevents small food from falling through and works well for vegetables or seafood. Wider spacing drains grease faster but sacrifices small-food support, so pick based on what you grill most often.
Will A Replacement Grate Void My Grill’s Warranty?
Aftermarket grates typically don’t void the warranty on the rest of the grill, but check your owner’s manual for any specific exclusions. Replacing a worn grate is generally considered routine maintenance rather than a modification.
Closing Remarks
The right replacement rack depends entirely on the grill sitting in your backyard. Nexgrill owners get the best value from picks 1 and 5, while Weber Spirit households should start at picks 2, 3, or 6. Specialty setups like Bull outdoor kitchens have their own dedicated parts, and Americana value grills can be brought back to life without much fuss. Match the model number, pick the material that fits your cooking style, and the rest is just a quick swap.
