The 2-inch Low-Profile Rubber Swivel Caster Set provides smooth and easy work stand mobility when portability is needed and rugged worktable solidity when a stationary placement is desired. 2 of the 4 casters feature an easy-to-use foot-operated, side lock brake: When foot levers are in a raised position, the casters roll smoothly and quietly and when the foot levers are lowered, the wheels will lock and your work platform will be tightly held in place. Because these casters deliver a smooth swiveling action (360° capacity) you can move your work stand in any direction with ease. Constructed of premium rubber and zinc-plated steel, these high-performing components are highly durable . Each caster has a weight-bearing capacity of 66 lbs. (264 lbs. for set of 4), so this handy set is perfect for your light to medium-duty applications. Ideal for use on hard flooring such as cement, tile, wood, ceramic and linoleum, etc. Color: Silver/ Black.
