This replacement set of Gander Mountain PermaChill Cooler Feet provide for both an anti-skid and sliding cooler bottom. The feet are reversible, meaning one side provides slip protection, and the other side makes sliding the cooler a breeze. The anti-skid side is great for keeping the cooler in place while traveling, while the easy-slide side works for passing the cooler around the floor of a boat or garage. Fit PermaChill 50L, 70L, and 120L cooler sizes. Comes in pack of four.
