Designed to work smoothly with any belay device, the elegant Airlock2 Screwgate is simple, easy to operate and won’t lock up under body weight.
Full-service belay biner
The AirLock's distinctive, curvy shape and ultra-rounded surfaces allow the rope, carabiner, and ATC to interact with exceptional smoothness during belays and rappels.
Large internal volume has huge carrying capacity - holds all the bulky knots, harness webbing and stacks of runners you could ever need.
Its unique shape helps to stabilize it on your harness by resisting rotation (the dreaded "biner flop") during belaying
Wide top and bottom curves – belay on either end although optimum position is with big end towards the belaying device and the small end on the harness
