4 in Side Mount Plate Caster Wheels Heavy Duty 1200 LBS Thickened L-Shaped, 360° Swivel, Locking Dual Brake, Quiet Non-Marking Black Wheels, Set of 4 for Furniture, Carts, Cabinet

HIGH QUALITY HEAVY DUTY CASTERS - These caster wheels are constructed from high strength industrial grade steel and premium thermoplastic rubber material. The L-shaped top plate design distributes the pressure borne by the rubber wheels and stabilizes the connection between the casters and the item. This set of 4 casters can support up to 1200 pounds, with each wheel holding up to 300 pounds, reducing fatigue from moving heavy items and avoiding the risk of injury. LOCKING BRAKE SYSTEM - These furniture wheels feature dual brakes that lock the bottom plate's rotational direction and the caster's forward direction simultaneously, engaging through foot action to hold heavy items securely in place and prevent potential hazards.

360° SWIVEL - The double ball bearing structure enables the desk wheels to swivel 360°. The built-in precision ball and steel balls ensure smooth rotation and stable movement, allowing heavy items to be moved with minimal effort, saving your back and energy. QUIET AND NON-MARKING - The caster wheels are made of thermoplastic rubber, which combines the elasticity of rubber with the plasticity of plastic. This effectively cushions vibration and reduces friction, producing minimal noise in indoor environments and achieving non-marking gliding on various types of floors to protect them. WIDE APPLICATIONS - This set of heavy duty caster wheels includes 4 x 4 inch caster wheels, 20 screws, and 1 screwdriver to facilitate easy mounting of the locking casters to carts, workbenches, furniture, shelves, and other items.

The caster's L-shaped top plate design saves mounting space, and it can also be suitable for small DIY projects
