Shelf: Under-grill mats
Size: 79 x 52
Cut for: Weber Genesis, Blackstone griddles, Fire pits and patio tables

Deck boards and patio stones tend to soak up burger drippings and stray charcoal sparks. We built this mat from fiberglass with a double-sided silicone coat so liquids pool on the surface instead of sinking into the wood. It rolls out flat under larger cabinet grills, wide griddles, and fire pit tables.

Double coated fiberglass

The core is fiberglass fabric sealed on both sides with thick silicone. Hot grease and stray embers sit right on top of the surface rather than soaking through to the porch below.

Grips the deck boards

The textured finish keeps the mat from sliding around while you wheel a heavy griddle or smoker into place. It stays planted on wood, composite boards, and poured concrete slabs.

Rinses off with water

Sauce, marinade, and black grease wash right off with a garden hose and some dish soap. You can wipe it down with a rag and let it dry in the sun before the next cook.

Checking your footprint

Measure the legs and grease cup position on your cooker before laying this down. You want enough room on all four sides so stray pops from the fire land on the mat.
