DMM Shadow Locksafe

The Shadow strikes an ideal balance between low weight and useability. Weighing just 50 grams thanks to I-Beam construction, you can carry several Shadows before the weight starts to tell. Despite low weight, it is big enough to use in winter with gloves on. A locking carabiner for all situations.

DMM PerfectO Locksafe

The PerfectO is a compact true oval connector that minimises the eye-to-eye length whilst maintaining usability and easy one-handed use. Their shape provides effective centring of loads and the fully rounded rope bearing areas increase carabiner and rope longevity.

Its keylock nose allows snag-free operation.

This is the smallest Locksafe gated carabiner that DMM makes and is 14mm shorter than an Ultra O yet still retains a strong construction. Available in standard and removable captive bar versions, with or without iD.

DMM Boa HMS Kwiklock ANSI 30kN

The heavy duty version of the 25kN Boa looks very similar, but is hot forged from 14mm rather than 12mm bar to give it the 30kN major axis rating required for rescue loads. The massive curved basket copes with even the busiest rigging set up and still allows devices to settle comfortably. The impressive size and ergonomics ensure it can be operated by even the largest hands with the chunkiest of gloves.

DMM Boa HMS Locksafe ANSI Titanium Gold

DMM Revolver

The Revolver's pulley wheel reduces friction on ropes moving through the carabiner. Placed where the pitch changes direction, it reduces rope drag and makes upward movement easier.
The Revolver can be used in an improvised hauling system to help your second over a crux, haul kit bags, or rescue your partner from a crevasse. Where normal carabiners in these systems cause energy to be lost as friction, the Revolver's pulley wheel makes hauling easier by converting more of your energy into movement.
A Revolver on your rack lets you reduce rope drag and make efficient mechanical advantage systems without the need for additional devices.
