4" x 1-1/4" Poly-Pro Wheel Swivel Caster w/ Brake - 300 lbs. Capacity
Product Overview
This Poly-Pro swivel caster combines a 4-inch non-marking polyurethane wheel with a polyolefin core, guarded precision ball bearings, and a top lock brake. The polyurethane tread is mechanically locked to the core and provides a firm, smooth-rolling surface for indoor carts and equipment.
The caster is rated for loads up to 350 lbs and has a 5-1/8-inch overall height with a 3-13/32-inch swivel radius. It uses a 4-inch by 4-1/2-inch mounting plate with a bolt-hole pattern ranging from 2-5/8 inches by 3-5/8 inches to 3 inches by 3 inches. For outdoor applications with prolonged UV exposure, consider a Polymadic wheel caster made with UV-resistant materials.
