Falls from ladders are the leading cause of fatalities in the Australian roofing trade. The Lock Jaw Ladder Grip clamps to your guttering in 5 seconds, eliminating lateral movement and keeping you compliant with Safe Work Australia obligations on every job.
WHS Regulations r.306 — A person must not carry out work on a ladder if there is a risk of the ladder moving unless the ladder is secured against movement. Lock Jaw provides a verifiable, documented way to meet this obligation on every roofing job.
