High-quality drawer glides (slides) are critical to supporting the smooth and silent movement of your cabinet drawers over years of hard use. The more weight your drawers carry, the more important undermount, soft-close drawer glides are. Weak glides could lead to sagging, loose, or stick cabinet drawers.
Undermount, steel, soft-close drawer glides should extend to provide full access to the entire drawer. Ball bearings and steel guides provide smooth operation and long wear. Mounted beneath the drawer box, the glides should be rated to support a heavy load: at least 90 pounds. Adjustable glides with a soft-close (anti-slam) dampening system will be almost silent when opening and closing the drawer.
