Our side-mount file cabinet rails are made of cold-rolled steel, offering high hardness, excellent toughness, and resistance to deformation. They have outstanding anti-rust and anti-oxidation properties and stay bright and new even after long-term use. Featuring ball bearing construction, they rotate smoothly, remain stable and durable, and help reduce noise during the pulling process.2. The slide rail is a two-section design. Even when pushed or pulled forcefully, it can slowly close smoothly. The buffer rubber pads effectively absorb impact during switching, reduce noise and wear, extend their lifespan, and deliver a quiet, smooth user experience.INSTALLATIONIt needs to be used in pairs (one on the left and one on the right).
