Restore the jaw-adjusting crank on your folding workbench with this direct-fit replacement handle arm (part number 723541). Designed as the hand crank for the winder that opens and closes the vise jaws, it’s a black plastic crank about 210 mm long × 170 mm across the handle, and mounts onto the winder shaft in the standard Workmate-style mechanism. Fits a wide range of Workmate and bench models including Black & Decker WM300, WM301, WM529, WM535, WM536, WM550, WM625, WM626 (and WM626‑B/C variants), WM700, WM747, WM750, WM800, WM825, WM835 and equivalent Stanley/Workmate benches. Simple to install — slides onto the shaft and secures with the original pin or set screw to restore smooth jaw travel.
