Grivel Master Pro Belay Device, Ascender, Use for Multiple Climbers

A tube device for belaying the leader and one or two seconding climbers. Extra friction V-slots add more control and smoothness. In addition, the small tail is used as an aid to easily increase friction when desired. When belaying seconds up it can be used as an autoblocking belay directly from the anchor point. Can also be rigged as an ascender using the autoblock technique. Cooling Technology inner holes allow more airflow therefore less heat build and a lighter object. It also gives easier access to remove snow/ice and mud.
