Original DeWalt swivel grip (part no. 820834) — a direct replacement clamping knob designed to restore the tightening action of Workmate-style folding benches. Molded plastic with a contoured hand grip for positive control, it fits onto the bench clamping spindle and replaces worn or cracked knobs so the jaws lock up securely again. Typical bore/fit is about 20 mm with the clamping face/stop around 30 mm, and it is listed as compatible with a range of Workmate/bench models such as WM225, WM300, WM536, WM550, WM625 and WM626, making it a small but essential power tool parts replacement to get your bench back to work.
