4-1/2 x 6-1/4 Plate Casters | 3 in Wide Tread

These 3 in wide heavy duty casters carry plant trucks, dies, and fixtures. Casters in this collection range from 2,000 to 2,500 lb per caster. Swivel and rigid models are listed on 4-1/2 x 6-1/4 in plates. Kingpinless swivels hold up better under shock and repeat loads. Softer polyurethane or soft rubber or TPR tread is the better pick when the floor has chips or grit. Match the 4-1/2 x 6-1/4 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. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy. Heavy duty hub: heavy duty casters. Plate aisle: plate casters.
