The ShelterLogic 12 ft. Firewood Rack with Cover has an open design that provides excellent ventilation for seasoning your firewood. It keeps the wood off the ground and free from moisture and infestations, making it more efficient and ready to burn. The included polyester cover can be adjusted to fit up to 24 in. lengths of split wood and moves up and down the firewood rack with the level of the wood, allowing for quick and easy access.
