⚡ At a Glance
- • Efficiency: Sealed ball bearings deliver 91% mechanical efficiency
- • Best for: Crevasse rescue teams, hauling and self-rescue on 8–11 mm ropes
- • Not ideal for: Use on ropes smaller or larger than the 8–11 mm range
Lightweight progress-capture pulley for 8–11 mm ropes with sealed bearings delivering 91% efficiency. At 85 g and with a lockable cam, suitable for crevasse rescue, hauling and emergency ascents.
Smooth, low-effort hauling – thanks to sealed ball bearings
Sealed ball bearings reduce internal friction and allow the sheave to turn more freely under load, producing a reported 91% mechanical efficiency. Lower friction means less force is needed to move the same load along the rope.
Reduced hauling effort and steadier movement when rigging systems for rescue or hauling tasks, helping teams work with greater control and less fatigue.
Easy to carry on long routes – with very lightweight construction
Compact engineering keeps the unit's mass to just 85 g without adding bulk to a kit. The small footprint fits alongside other technical gear in a rucksack or rescue pack.
Minimal weight and compact size make it simple to include in alpine or glacier kits, where every gram and cubic centimetre matters.
Switchable pulley modes – with a lockable cam for versatility
A cam mechanism can be raised and locked to convert progress-capture function into a simple pulley configuration. The same mechanism supports use as an emergency ascender when needed.
Useful for teams that need one piece of kit to perform multiple ropework roles during rescue, hauling and emergency scenarios.
