DMM Aero HMS Locksafe climbing triple action carabiner is designed for climbing and mountaineering and features an automatic closing/opening system that requires three movements: sliding, rotating, and then pressing the lever.
Aero HMS Locksafe is a pear-shaped carabiner, with a solid section, extremely resistant to wear and provides excellent rope control.
The triact-lock mechanism makes Aero HMS Locksafe a top-of-the-line product in terms of safety and practicality, easy to handle even when wearing gloves.
The Taperlock profile prevents the carabiner from accidentally snagging on the rope, devices, or anchors, making maneuvers smooth and without unexpected risks, improving performance and maneuvering effectiveness.
