Rear Grease Gate for Blackstone Griddle, Griddle Grease Gate

The Verdict

If you’ve cooked on a Blackstone for more than a week, you know the struggle: diced onions, stray rice grains, and crumbling sausage all migrate toward the rear grease trough — then clog the drain hole and sit there burning until you scrape them out with a spatula and a lot of swearing. The Rear Grease Gate for Blackstone Griddle is a $15-ish piece of stainless steel that claims to end that. After testing it across a dozen cooks, here’s the honest breakdown.

What you actually get

The package contains a single stainless steel gate that clips into the rear grease trough of compatible Blackstone griddles (the 22”, 28”, and 36” models with rear-drain design). It’s not magnetic — it uses a friction-fit clip that snaps against the trough walls. There are no screws, no adhesive strips, and no tools required. The gate itself measures roughly 1.5 inches tall and spans the full width of the trough opening. That’s it. One piece, one job.

Real-world performance

The gate does exactly what it claims: it blocks food debris from sliding into the grease drain. The clever part is the bottom edge — it sits flush against the griddle surface, so there’s no gap for small particles to sneak under. Meanwhile, the top edge clears the cooktop, so liquid grease still flows over the top and into the cup. That’s the design insight that makes this work — it’s a dam for solids, not a wall for liquids.

During testing, I cooked a full pound of bacon, a batch of hash browns, and a stir-fry of peppers and onions. The hash browns shed flakes that would normally gum up the drain; with the gate in place, they piled up against it and were easy to sweep into the trash after the cook. The bacon grease flowed over the top without issue — no backup, no pooling.

What buyers consistently praise

The 4.7-star rating from 235 reviews isn’t accidental. The most common sentiment is surprise at how well a simple piece of metal works. One reviewer wrote, “Wish I’d bought this a year ago. No more digging burnt onion bits out of the grease cup.” Another noted, “Fits my 36” Blackstone perfectly. Solid steel, not flimsy.” The durability gets consistent mention — multiple buyers report using it for months with no warping or rust, which is notable given the high heat and moisture of griddle cooking.

Where it falls short

Two honest complaints. First, the gate has no drainage hole — it’s a solid barrier. If you’re cooking something with heavy liquid grease (like a big batch of burgers), the grease pools behind the gate until you remove it. You can slide it out mid-cook, but that’s an extra step. Second, the friction-fit clip works well when clean, but after a few cooks it can get sticky with grease buildup. You’ll need to wipe it down regularly, or it becomes harder to remove. One reviewer summed it up: “Works great, but I have to clean it after every use or it gets stubborn.”

Who should buy this

• Blackstone owners who cook vegetables or rice on the griddle — these are the worst offenders for clogging the grease trough. This gate solves that specific problem.
• Anyone who hates scraping burnt food out of the grease cup — the gate saves you 10 minutes of cleanup per cook.
• Skip it if you have a side-drain Blackstone — it won’t fit. Check your model before ordering.

FAQ

Does it fit all Blackstone griddles?
No. It fits models with a rear grease trough — typically the 22”, 28”, and 36” standard griddles. Side-drain models (like the Adventure Ready series) are not compatible.

Can I leave it in place while using a griddle cover?
Yes. It sits inside the trough and doesn’t interfere with the lid or cover.

Will it rust?
The stainless steel construction resists rust, but only if you dry it after cleaning. Leaving it wet in the trough will eventually cause surface corrosion.

The verdict

Buy it if you own a rear-drain Blackstone and want to stop fishing food bits out of the grease cup. Skip it if you only cook steaks and burgers with minimal debris — you won’t see the benefit.

Rating: 4.6/5 — It’s a niche accessory, but for Blackstone owners, it solves a real annoyance with minimal cost and zero installation hassle. The lack of a drain hole keeps it from a perfect score, but for the price, it’s a solid upgrade.
