No need to turn a knob or pull a handle—these slides open a drawer with a light push. They're often used in sanitary environments where you need to limit the surfaces you touch. They fully extend for convenient access to the back of drawers. All have ball bearing rollers for smooth, quiet operation. Mount them to the sides of drawer openings in cabinets. To remove your drawer from its cabinet, use the release lever to separate the inner part of the slide from the outer track.
