The ShelterLogic 12 x 20 x 8 Feet Run-in Shed-in-a-Box is a perfect combination of utility inconvenience. The in-a-box design allows it to be assembled quickly and easily, right from one package. Once it's put together, the high-quality, rust-resistant steel construction and patented Shelterlock Steel stabilizers make sure it's secure and tough enough to weather the elements season after season. With the heat-sealed seams making the shelter waterproof, and protective boots on every corner, you can be sure it's safe for both equipment and animals.
