DeWalt 861840-03 — genuine DeWalt rear locking lever for mitre/chop saws. Smooth, black molded lever with a spring-actuated push-button release designed to lock the saw head or fence in position; it replaces the worn or broken rear lock used to secure mitre and table saw angles. This part is commonly used as a direct replacement on a range of DeWalt mitre and table saw models — example fits include DWS774, DWS773, DWS771, DWS777, DW711 and DW701 — and is listed as part number 861840-03 on official parts diagrams. If your saw’s rear lock is cracked, loose, or the push-button no longer holds, this original DeWalt lever restores firm, repeatable locking without adjustment.
