When used with a chest strap and a rope clamp, the Petzl Croll makes for a simple and efficient system for ascending fixed lines. The angled attachment hole keeps the device properly aligned on the chest.
- Chrome-plated steel cam with angled teeth and self-cleaning slot securely grips the rope, even in muddy or icy conditions
- Ergonomic trigger allows one-handed installation and removal
- Upper hole is used to attach shoulder strap
- Safety catch prevents the cam from opening too far, thus helping to keep the rope captured for added safety
