A scattered formation can allow a reptile or small animal to climb to whatever desired height is comfortable. Approximately 21” long x 9 1/2” wide x 5 1/2” tall. Molded with bolts in the back and come with wing nuts for reinforcement as well as quick and easy mounting. Holes driled for free (not in acrylic)!
