Shower Door Top Roller Hanger
Replacement top hanger for framed sliding shower doors whose original roller cracked and whose OEM part is long discontinued — a 624 bearing (4 x 13 x 5 mm) becomes the wheel, clamped on an M4 x 20 screw through the 4.5 mm axle bore, so the outer race rolls on the existing track. The 64 x 24 x 5 mm plate carries two 4.6 x 11 mm slots giving 10 mm of height adjustment to re-square a dragging door, and the M4 screw head recesses 3 mm into the back so the plate sits flat against the door stile.
