Shelf: Under-grill mats
Size: 100 x 52
Cut for: Weber Genesis, Blackstone griddles, Fire pits and patio tables

Spilled marinade and hot grease have a way of soaking right into wood or stone patios. We cut this mat wide enough to sit under full cabinet grills, flat top griddles, or round fire pits. It unrolls flat and takes the mess instead of your boards.

Fiberglass core and silicone

A core of woven fiberglass gives the sheet body, while smooth silicone coats both faces. Stray grease beads up on top instead of soaking through to the wood planks underneath.

Grips the deck boards

The textured backing sits flat against composite decking, concrete, or treated wood. Wheels roll across it without bunching the corners up beneath the grill legs.

Stitched outer border

Heavy thread locks the cut edge so the layers do not peel apart after a rainy spring. You can hose off cold fat and hang it over a rail to dry.

Check your grill base

Take a tape measure across the footprint of your grill cart or fire pit table before ordering. You want enough border on all four sides to catch pops and splatters.
