A bearing retainer lock (30) for a drawer slide (12) has a detent pin (34) which engages within an opening (38) formed into a forward end (36) of a bearing retainer (26). The detent pin (34) is mounted to the slide member (16) to which the bearing retainer (26) is secured. A slot (60) is formed into the detent pin (34) such that sides of the detent pin (60) have a predetermined flexibility. The opening (38) in the bearing retainer (26) has two side portions (50) which are of selected widths to determine a flexibility of the opening (38). The size and depth of the slot (60) in the detent pin (34) are selected in combination with the width of the side portions (50) of the opening (38) such that the detent pin (34) will engage within and release from the opening (38) at a predetermined force.
