Furniture pull-out guide

Abstract

A furniture pull-out guide includes a guide rail with a hollow profile defining a base web, first and second longitudinal webs disposed at predetermined angles to the base web, and transition regions connecting the base web with the first and second longitudinal webs. The guide also includes a first axle moveable longitudinally with respect to the guide rail, at least a first roller rotatably disposed on the first axle, and at least a second roller disposed on the first axle adjacent to the first roller. The first roller and the second roller are adapted to rotate independently of one another.
