Height-adjustable roller for bottom edge of sliding door is mounted in frame member with angled slots accommodating angled pins on control slider extending through slots in frame
The roller (22) has two stub axles (28) engaging in bearing apertures (30) in a roller holder (24). The roller projects upwards from a slot between two flexible walls (32). Grooves (38) in the sides of the holder engage ribs (40) on the inner sides of a housing (26) which fits into an aperture (16) in the top surface (14) of a beam (12). The roller holder can move vertically in the housing. A slider (50) with two tilted pins (52,54) may be moved horizontally, and the pins engage in tilted slots (34,36) in the roller holder. Teeth (34) in one of the slots and on one of the pins prevent slippage.
