Rust-resistant galvanized steel construction. Modular pre-assembled panels. The 1 in kennel legs allow for easy cleaning when the unit is placed on a hard flat surface. Square corners at the bottom of each panel and gate better contain small pets. No holes to dig, concrete to mix or wire to stretch. Portability helps to prevent lawn damage. With vertical bracing. Set-up requires only one 1/2 in wrench for easy assembly. Frame design allows condensation to drain freely.
