【Three-piece rails】All three-piece rails are sliding, and the distance between the drawer holes is used to make it easier and faster to select and place items. The rubber pad ensures that the rubber pad does not touch the drawer switch. [Damping effect] The solid steel ball is smooth and automatically dampens the drawer when the damping pad touches the damping device to reduce noise. 【Easy to disassemble and assemble】Plug in the lock and pull it up for quick release. Pull out the rail on the side of the drawer, which is more convenient for regular cleaning, extends the service life and prevents the drawer from freezing for a long time. 【Surface Treatment】Selected high-quality materials, electroplated surface, rust-proof, scratch-resistant and wear-resistant, not easy to deform, thickened material, stronger load-bearing capacity.
