GRIVEL - ROLLER TWIN GATE - Carabiner Pulley
The Roller is a connector plus a pulley in a single piece of equipment. The goal is to reduce the friction of different maneuvers and make the job"lighter". Very useful in multi-pitch wall and for self or professional rescue. The idea permits to clip the carabineer directly into the required point: a belay point, into the harness or to a heavy load.
