Build your outdoor kitchen with confidence using the Summerset 40" TRL Pro Insulating Liner (GL-TRLPRO40)—a critical safety component designed specifically for 40-inch Summerset TRL Pro built-in grills. This heavy-duty liner allows for safe installation in combustible materials such as wood or composite cabinetry, giving you greater flexibility in outdoor kitchen design.
Constructed from premium #304 stainless steel, this liner is engineered for durability, corrosion resistance, and long-term outdoor performance. Its 1-inch thick, double-walled insulated design acts as a thermal barrier, preventing heat transfer from the grill to surrounding structures and significantly reducing the risk of damage or fire.
Precision-built for the TRL Pro 40" grill, the liner provides a secure, custom fit while maintaining proper airflow and clearances. The result is a clean, professional installation that enhances both safety and aesthetics in your outdoor kitchen.

Frequently Asked Questions
No. It is built specifically for the 40" Summerset TRL Pro built-in grill and is precision-cut to that body.
The grill it pairs with is the TRL Pro 40" built-in. Match the series as well as the width before ordering.
42" wide, 11 1/8" high and 22" deep. The opening is wider than the grill because the liner surrounds the grill body.
Cut to the liner, not to the 40" grill dimension, or the assembly will not seat.
Summerset lists it as required for combustible construction. If your island is framed in wood or composite, this is the component that makes the built-in installation viable.
It is a safety part, not a finish accessory, which is why it is specified alongside the grill rather than sold as an upgrade.
A 1" thick, double-walled construction acts as a thermal barrier between the grill and the surrounding framing.
That barrier is what keeps heat, grease and flare-ups off the cabinetry over the life of the island.
#304 stainless steel, specified for corrosion resistance and long-term outdoor performance in a part that gets built into the island permanently.
No. It is engineered to hold the correct airflow and clearances around the TRL Pro 40 once the grill is seated inside it.
The tight fit also closes the visual gap between grill and island for a clean built-in line.
