MIDWEST Universal Crate Casters(2Pk)-The MIDWEST Universal Crate Caster is designed to fit most wire crates by attaching to the intersection of any two cross wires. The casters provide portability and ease of movement with easy rolling, locking casters and come packed with two casters in each blister card. Why two per pack? MIDWEST suggests that you use only four casters on crates 30" or smaller, however on crates 36" and higher six casters maybe neccessary inorder to support the additional wieght.
