Abstract
Abstract On a guide for drawers and other such furniture parts, having a guide rail which can be fastened to the wall of a cabinet, and a runner rail which can be fastened to the drawer, these rails being displaceable relative to one another by means of at least one wheel mounted on the front end of the guide rail and at least one wheel mounted on the rear end of the runner rail, an approximately rectangular adjuster is disposed on the front end of the guide rail in contact with the runner rail and is held displaceably and removably on the vertical web of the guide rail. The adjuster has on its side facing the flange of the runner rail a ramp surface which, by the displacement of the adjuster, can be brought to bear against the confronting edge of the runner flange.
