The Petzl Progress Adjust-I is a single adjustable progression lanyard that allows, when combined with another lanyard, continuous connection for all types of progression (rope ascent, moving along a traverse line). 

 

The rope adjuster allows the length to be quickly and easily adjusted. 

 

Reversible, the Adjust rope adjuster can be placed on the anchor or on the harness ventral attachment point.

 

Individual identification marking on the plastic sheath, for tracking the equipment throughout its lifespan.
