Drawer Sliding Rails are made of metal material, which is strong and suitable for long term use. Drawer Slides are designed for furniture installation to improve drawer functionality. Soft Closure Drawer Sliding Rails feature a push-to-open mechanism; gently press the panel and the drawer opens smoothly for easy operation. These Drawer Slides use a bottom supporting installation method. When the drawer is pulled out, the tracks on both sides remain hidden, maintaining a clean and neat appearance. The simple design of the Drawer Slides complements various cabinet styles and enhances overall aesthetics.
