Slotted Awning Window Scissor Stay Arm
A replacement arm for the flat scissor-stay linkage inside older awning windows, where cracked OEM arms are no longer sold. It is a 158 x 18 x 6 mm bar with a fixed 5.5 mm M5 pivot hole and a raised thrust pad at one end. Two 5.5 mm wide slots let you set the other pivots where your old arm had them: the middle slot runs 52–78 mm from the pivot and the end slot runs 119–143 mm. Measure your old arm before ordering, then fit it with M5 bolts, washers and nylock nuts.
