The Petzl Ok Ball-Lock oval carabiner for pulleys, blockers and fall arresters is made of alloy and features an innovative and practical automatic opening / closing system.
Its oval shape allows you to optimally and quickly position the various devices for maneuvering and progression.
The Ball-Lock is nothing but a triple-action automatic locking system with a locking indicator.
Furthermore, by combining the Captiv bar (), you will encourage the carabiner to be stressed on the major axis, reducing its overturning.
