American Outdoor Grill 24" Insulating Liner, 304 Stainless Steel

When you're setting an AOG T-Series or L-Series 24" built-in grill head into a combustible outdoor kitchen structure, this insulating liner isn't optional — it's the code-compliant, fire-safe barrier that makes the installation legal and the outcome predictable. Constructed from 304 stainless steel, it's built to handle the thermal demands of a working grill without corroding, warping, or requiring any particular affection.

The liner arrives pre-assembled and includes two hanging supports, so installation is a matter of positioning rather than puzzling. It drops into a cutout measuring 28 5/8" wide by 21 5/8" deep by 9" tall, with overall dimensions of 30.25" W x 22.25" D x 8.625" H — precise enough that you'll want to confirm your cutout dimensions before pouring concrete or cutting stone. At 33 lbs, it has the substance you'd expect from a properly engineered component rather than an afterthought.

Outdoor kitchens built from wood framing, composite materials, or other combustible substrates require this liner between the grill head and the surrounding structure. Skipping it isn't a shortcut — it's a liability. The liner creates the necessary thermal separation so your island stays a cooking destination rather than a cautionary tale.

Compatibility is specific: this liner is designed for AOG T-Series and L-Series 24" built-in grill heads. If you're working with a different size or series, verify fitment before ordering. When the match is right, installation is clean, the grill seats correctly, and you're cooking with the confidence that the structure around it is properly protected.

Stainless steel at this gauge doesn't need much from you in terms of maintenance — an occasional wipe-down to keep things presentable is about all it asks. The 304 alloy resists the outdoor elements that would shorten the life of lesser materials, making this a component you install once and forget about, which is exactly what a liner should be.
