Overview
A cam clamps the rope while a molded, dual-density overmolded handle gives the climber a firm grip in wet or cold conditions. The wide opening lets a gloved hand grab the handle, and an orange safety catch is easy to inspect.
Comfortable, gloved-hand grip and recognized certifications are the reasons to choose it for rope ascents and rescue work. It fits only the listed rope range, and this is the right-hand body only.
Who it's for
Rope access workers, cavers and climbers who ascend regularly and wear gloves will use the wide handle opening and the certifications. Anyone needing a left-hand version, or a lighter chest ascender, should check the other models.
Pros and cons
- Dual-density overmolded handle
- Wide opening for gloved hands
- Orange safety catch for inspection
- Certified for rope work
- Right hand only in this listing
- Limited to the listed rope range
- Instructions not included in the listing
- Several mixed materials
Performance notes
The cam grips the rope when loaded and slides when the handle is pushed up, which is how a handled ascender climbs. The dual-density handle holds grip in wet or cold conditions. Rope diameter outside the listed range will not clamp reliably.
