The Drawer System’s top deck is great for what it’s designed to do—holding tons of gear! But the deck (made of ultra-durable HDPE) can get a little slippery. The lightly padded, slip-resistant DECKED Traction Mat solves this problem. Perfect for holding things like coolers, cases, kennels, and pets in place—all while making it easier on your knees, elbows, and back should you be crawling around in your truck bed.
