Chest lock is very convenient to use. The fixing holes ensure efficient positioning during the climb; thanks to the wide groove of the rope, it fits perfectly to wide, bulging or rigid ropes, while limiting friction.It is compatible with ropes measuring from 8 to 13 mm in diameter.

Suitable for rope diameter of 8. 0 13. 0 mm. The two eyelets are positioned so that the clamp rests flat on the chest when used with waist belt and shoulder straps. The serrated clamping cam made of stainless steel is corrosion-resistant and has a cleaning slot to achieve the best operability in all weather conditions. With its large guide groove, it ensures great efficiency when climbing on the rope and reduces friction even with stiff or furry ropes. The Croll L chest climbing clamp from Petzl is particularly optimised for ropes with a large diameter.
