Featuring a 3-section fold design, the slide enables full extension of the drawer, allowing easy access to all contents inside. The ball bearing structure ensures smooth, silent gliding of the drawer during use. The slide rail has a detachable buckle on the back, simplifying the installation process. Its rear end is equipped with a rubber mute pad, reducing noise to as low as 35 decibels for a more comfortable home environment. With a special electrophoretic coating surface treatment, the slide offers superior rust resistance and oxidation resistance compared to ordinary models. Inside, dual industrial-grade bearing balls ensure smooth sliding even when the drawer carries heavy items. Additionally, a rubber crash pad—wear-resistant and impact-resistant—prevents collision noise, keeping operation quiet. This drawer slide set comes in black, with a quantity of 1 pair. The left and right side mounting clearances each require 0.5 in. (12.7mm). Before installation, please first push the inner ball bearing to the top of the slide, then attach the slide to the desired position. The product’s cardboard box includes 8 screws, and a detailed installation video is available in the product listing for reference.
