Plate Casters

These Colson plate casters are top-plate mounts for carts, racks, and fixtures on indoor floors. Casters in this collection range from about 200 to 1,250 lb per caster. Wheel diameters run about 2-1/2 to 8 in with 1-1/4, 1-5/16, and 2 in treads. Most mounts use a 4 x 4-1/2 in top plate. Treads include rubber, nylon, polyurethane (poly or urethane), polyolefin, and phenolic. Soft rubber or soft polyurethane is the better pick when the floor has chips or grit. Match plate size, overall height, and swivel or rigid before you place your order today. Read the listing for the exact tread and brake option shown. Confirm the rating on the listing before you buy. Keep the load on the rating printed for that SKU. Capacities below are per caster unless a listing says set. Full Colson brand aisle: Colson casters. Broader plate aisle: plate casters.

Choosing Colson plate casters

Load: plan on three casters carrying a four-caster cart [S2]; at 1,100 lb each, a common rating here, that is about 3,300 lb, and the 1,250 lb top rating covers about 3,750 lb.
Mount: most Colson plate casters use a 4 x 4-1/2 in top plate; 2-1/2 x 3-5/8 in and 2-11/16 x 3-5/8 in plates are listed too; check the bolt spacing on your frame against the plate size.
Floor: on Colson plate casters, rubber and polyurethane are kinder to tile and finished floors; nylon, polyolefin, high-temp phenolic, phenolic and stainless steel roll easier under heavy loads on smooth concrete.
Rig: swivel and rigid Colson plate casters are listed, with top lock brake, total lock brake and side lock brake options.
Heat: among Colson plate casters, the highest listed range is -40°F to 600°F on rubber; check the temperature field on each listing before oven or hot-room use.
