Product Overview

The Summerset TRL Pro 40" Insulating Grill Liner (GL-TRL40) is a safety requirement when installing Summerset TRL Pro 40" (TRLPRO40) in an outdoor kitchen island built with any combustible materials — lumber, OSB, resin composite, or similar framing. Building codes in most jurisdictions require an insulated liner when combustible frame construction is used. The liner is a double-walled stainless steel sleeve that fits exactly to the grill model, creating the required heat barrier between the grill and the island frame. #304 stainless steel. Gold Standard Lifetime Warranty.

Key Features
  • Required for Combustible Island Builds: If your outdoor kitchen island is built with lumber, OSB, or any combustible material, a grill liner is required by building code to provide the necessary heat barrier.
  • Custom Fit for Summerset TRL Pro 40" (TRLPRO40): Designed specifically for Summerset TRL Pro 40" (TRLPRO40) — not a universal liner. Incorrect fit will not provide the required clearance.
  • Double-Walled Stainless Steel: Double-wall insulated construction creates the required thermal barrier between the grill and the island frame.
  • Self-Supporting Ledge: Built-in ledge supports the liner during installation and keeps it properly positioned around the grill.
  • Drop-In Installation: Liner installs into the island cutout first, then the grill drops into the liner — same process as standard installation.
