*Does not fit TRL32 or TRLPRO32 (these are compatible with item #GL-TRLPRO32)
Ensure a safe, code-compliant outdoor kitchen installation with the Summerset 32" Built-In Grill Insulating Liner, engineered specifically for Summerset 32-inch grill. This essential component allows you to confidently install your grill into combustible materials such as wood or composite cabinetry, protecting both your investment and your outdoor living space.
Constructed from premium #304 stainless steel, this liner is built for long-term durability and resistance to outdoor elements. Its double-walled, insulated design (approximately 1-inch thick) significantly reduces heat transfer from the grill to surrounding structures—helping prevent damage, discoloration, and fire risk.
Custom-engineered for a precise fit, the liner integrates seamlessly into your outdoor kitchen, creating a clean, professional built-in appearance while maintaining proper airflow and safety clearance around your grill.
Sizzler-series liner (GL-SZR32). The TRL Pro 32 uses GL-TRLPRO32 instead.
Fitment is based on the manufacturer's stated model compatibility. Confirm your exact model number before ordering.
Frequently Asked Questions
It fits the SIZ32, SZR32, SIZPRO32 and SZRPRO32 built-in grills.
It does not fit the TRL32 or TRLPRO32. Those two take a different part, the 32" TRL and TRL Pro liner.
33" wide, 9 3/4" high and 22" deep. That is the liner's cutout, and it is what the island should be framed to.
Read the model designation printed on the grill and compare it to the four codes above. SIZ, SZR, SIZPRO and SZRPRO take this liner; TRL and TRLPRO do not.
The two liners have different cutout heights, so ordering the wrong one means recutting the island, not just swapping a part.
It lets you install the grill into combustible materials such as wood or composite cabinetry. Summerset lists it as required for combustible island installations.
It also shields the surrounding structure from heat, grease and flare-ups during normal use.
The liner is double-walled at roughly 1 inch thick. The gap between the walls is what significantly reduces heat transfer to the structure around the grill.
#304 stainless steel, chosen for durability and corrosion resistance since the liner is permanently built into the island and not easily replaced.
Yes. The liner is custom-engineered to the 32" grill body so that proper airflow and safety clearance are maintained after the grill is dropped in.
The result is a flush, professional-looking built-in rather than a grill sitting in an oversized hole.
