Abstract
One of two drawable furniture parts have an outer rail made from a triangular hollow section having a lengthwise slot for receiving an inner rail. The outer rail is mounted on an inner rail and rides on a triangular array of balls. The inner rail is made of two superposed U sections whose inside legs are flatly welded together and have their edge portions bent apart to form a track for the upper row of balls. The two lower rows of balls are received in the triangular hollow section below the bent edge portions.
