The Alturi 42" Grill Liner (GL-42) is what makes it safe and code-compliant to install the Alturi 42" built-in grill into an island framed with combustible material — wood studs, composite cabinetry, or any custom build that is not solid masonry.
Constructed from double-lined #304 stainless steel, the liner creates a thermal barrier between the appliance chassis and the surrounding structure. The double-wall construction is the working part: it traps an air gap that does the insulating, rather than simply putting one sheet of steel between the heat and the framing.
The 42" liner is the largest in the Alturi range and the one most likely to be the deciding factor in a build, because a 42" cutout leaves the least margin between the grill body and the framing on either side.
Precision-built for a seamless fit, it disappears once the appliance is set, leaving the clean built-in appearance you paid for. Backed by the American Made Grills Gold Standard lifetime warranty on stainless steel liners. Browse the rest of our grill liners to match a liner to every cutout in the island.

Frequently Asked Questions
The Alturi 42" built-in grill, and only that chassis. It is the largest liner in the Alturi range.
A 42-inch cutout leaves the least margin between the grill body and the framing on either side. Less air around the chassis means less room for heat to dissipate before it reaches the structure.
That is why on a 42-inch build the liner is often the deciding factor in how the island gets framed.
Wood studs, composite cabinetry, or any custom build that is not solid masonry. If your island is one of those, the liner is required.
Double-lined #304 stainless steel. The two walls hold an insulating air gap between the appliance chassis and the surrounding structure.
It is what supports compliance with those requirements for combustible construction. Check your local code as well before the island goes up.
No. It is precision-built to sit invisibly behind the Alturi 42" built-in grill once the appliance is dropped in.
