This collection holds Quantum Storage Wire Shelving, Bins & Carts casters with polyurethane and metal wheels, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 150 to 1,200 lb per caster. Wheels in this category range from 17-7/8 up to 40 inches in diameter with 8-3/8 to 11 in tread widths. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Metal wheels roll with low effort and handle debris and heat. They are loud and can mark finished floors. Match the stem size and thread before you order. 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.

From product titles and fields [S1].

Chrome or epoxy

Chrome wire is bright and easy to wipe, and suits dry rooms. Epoxy coated wire stands up better to damp areas, and the colors help mark storage zones.

Shelf rating vs unit rating

The ratings are per shelf with the load spread evenly. Once a unit is put on casters, the casters set the real limit, so add up the full load and check the caster rating too.
