Advantage
The threaded casters are made of PA (nylon), which is wear-resistant and pressure-resistant, with high hardness and greater load-bearing capacity, ensuring smooth and safe movement. The thickened carbon steel bracket is chrome-plated on the surface to prevent rust and corrosion.
The double-bearing design allows the wheels to move smoothly and quietly when bearing load. The 360-degree swivel design is easy to maneuver, allowing for smooth turns and precise navigation in tight spaces.
With brake design, the wheels can be easily locked to prevent sliding.

Instruction
Threaded design, with nut, washer and wrench, easy to install on furniture, can be used to replace old casters. (2mm/0.08" thin spanner suitable for screw fixing nut installation)

Note:
Please note that the load capacity of 4 wheels can only be calculated as the load capacity of 3 wheels. Because the road surface is uneven, the force on the 4 wheels may be uneven.
