Grivel Roller Twin Gate Carabiner

Minimal carabiner with integrated pulley and Twin-Gate system (gate-wire).

Small and light carabiner with integrated pulley, motion transmission part consisting of a disc rotating around its axis. Opening by Twin-Gate wire-gate system, which does not require any additional maneuver (e.g. screwing), making it safer and faster than other systems. Furthermore, it allows to avoid accidental openings that can occur for example due to contact with the rock, due to incorrect passage of the rope due to involuntary hand pressure. Two openings also allow greater resistance than one. Finally, it maintains its functionality over time and does not fear the presence of dust, earth, ice like other systems. The gate-wire combination facilitates its use even with gloves, and allows you to easily attach all types of devices (brakes). The pulley helps to reduce the friction that is created during the various maneuvers and also helps to reduce wear on the carabiner. Ideal for self-rescue maneuvers on glaciers, mountaineering and climbing. Individually tested, with the date of testing and progressive number laser-marked on it.
