HD-24 series plate casters with a polyurethane tread on a polyolefin core, in gray, blue and red, each as a swivel or rigid. At 275 lb per caster, four carry about 1,100 lb on a level floor, which suits utility carts, maintenance carts, bakery racks and stock carts.

Polyurethane on polyolefin

A polyolefin core keeps the wheel light and unaffected by water and most cleaners, and the polyurethane tread adds grip, quiet rolling and floor protection. It is a common choice for indoor carts where hard plastic would be too loud and rubber would wear too fast.
