DMM Captain

The DMM Captain is an innovative, high-strength hook designed for safe and stable positioning during work at height. Its unique design makes easy placement and controlled sideways movement (traversing) on complex structures such as trees or industrial structures straightforward.

The DMM Captain is an advanced tool for modern arborists and workers at height. This self-placing hook is carefully designed and tested with DMM's characteristic focus on detail and safety. The rotating D-shackle counteracts misplacement by destabilising the hook at the wrong angle, and works perfectly with the sculpted hook shape for reliable attachment – even on remote anchor points. Once placed, it provides a nominal breaking strength of 23 kN (depending on anchor strength).

When the work is done, the Captain is easily fitted to the harness, minimising the risk of the hook snagging. Ideal for work between or within complex structures, such as tree crowns or steel structures.
