These spring-loaded slides keep a drawer securely latched when closed. Pushing the drawer in about 1/8" pops it open. An integral quick-release lever quickly separates the drawer from the main slide, and two ball-bearing races ensure smooth operation. 100 lb weight capacity based on the 18" length. Side clearance is 1/2" plus 1/32" minus 0 each side. Requires at least 6mm clearance between the drawer back and cabinet back to allow actuation of the touch-open mechanism. Slides are 1 3/4" high. Breathing tabs self-adjust to variations in side clearance. Zinc-plated steel. Sold in pairs with mounting screws and instructions.
