Total Lock Plate Casters | 4 x 4-1/2 | 4-8 in

These heavy duty total lock casters lock both the wheel and the swivel so the cart stays put. Casters in this collection range from 600 to 1,250 lb per caster. Sets of 4 are rated 2,400 to 5,000 lb per set. Wheels include phenolic, red poly on iron, and orange poly on aluminum on 4 x 4-1/2 in plates. Sets of 4 show the combined set rating on the title, so divide by 4 for the per caster load. Softer polyurethane or soft rubber or TPR tread is the better pick when the floor has chips or grit. Match the 4 x 4-1/2 in plate, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place, rigid casters for straight travel, and add a brake when the cart needs to stay put. Total lock aisle: total locking casters.
