3" Casters - 03 Series Low Profile - up to 500 Lbs

These 3 in low profile casters carry machines, fixtures, and low carts where height is tight. Casters in this collection are rated 500 lb per caster. The wheel is 3 x 1-3/4 in polyolefin, in swivel and rigid models. Polyolefin resists water and many chemicals. It is hard, so it is loud on rough floors. Match plate size, 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. Capacities below are per caster unless a listing says set. 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. Check the floor type and the heaviest load the cart will carry before you choose. Low profile aisle: low profile casters. 05 series: 3 casters 05 series low profile.
