A slip-on self-locking automatically articulating emergency brakeing system for ladders is described. Consisting of a metal plate as the complete raw material required for the manufacture of a set of two brakes, one brake designed to fit the left hand side rail, and one brake designed to fit the right hand side rail of said ladder. A plurality of protrusions diverge from the body (22) of each brake, including a jug handle type lug (20) which most nearly encircles a rung of said ladder, a slide plate (12) which engages the rear portion of said ladder rail. A slide plate clasp (14) to prevent lateral movement of the device, and structuraly induced incisor column (10) and incisor (8) for use as a perpendicular brakeing mechanism due to right angle reduction.
