When you need to move heavy loads with confidence, the TAYLOON 4-inch heavy-duty stem casters deliver a reliable, quiet glide for carts, furniture, workstations, and more. This set of 4 features threaded stems sized at 3/8"-16UNC x 1", designed for sturdy, durable performance. The system is rated to handle substantial weight when load is distributed across all casters, giving you flexibility for demanding setups and frequent repositioning.

Robust construction with smooth, quiet motion

Built from thickened steel and paired with high-quality polyethylene wheels, these casters are designed to roll with a smooth, silky feel on hard surfaces. The PU rubber wheels minimize noise and resistance, while double ball bearings support effortless movement—so you can relocate equipment without disrupting surroundings.

Secure locking for safety and stability

The secure double locking mechanism locks both the swivel and the wheel. This feature helps keep your trolley, cart, or mobile furniture firmly in place during loading, unloading, or precision positioning. Each 4-caster set also includes locking nuts and a wrench for quick, secure installation.
