The Hettich KA 4932 ball bearing over extension drawer slides are a telescopic precision over extension drawer slide with cushioned in and out stops and a positive hold-in detent. The KA 4932 is made of chromated steel with precision ball bearings and provides a smooth sliding action and high lateral stability to reduce the wiggle in the extended drawer.
Over extension drawer slides provide an extra extension of the drawer box so that the back of the drawer is still accessible even when something like a countertop over hangs above the drawer. The Hettich KA 4932 over extension drawer slides have 1-1/2" of over extension so that the back of the drawer box extends past the face of the cabinet by 1-1/2".
