Put your wire shelving on wheels and you can rearrange your store room any time you want, or wheel clean dishes, pots, and pans from the dishroom to the kitchen. This universal wire shelving caster set makes it incredibly easy. Unscrew the feet at the bottom of the wire shelving support posts, slip the 1" sockets of these casters on the posts, tighten the Allen screws on the casters to secure them, and you're rolling on 5" grease-resistant polypropylene wheels. Each of the swivel casters has a locking side brake, so you can set shelving in place without worrying about it. Each caster has a load capacity of 220 Lbs., with an operating temperature range of 14ºF to 212ºF. The set of four universal wire shelving casters weighs 9 Lbs.
