Petzl Rack Coborator Alpinism

Brake bar descender for long descents

RACK is an easy-to-use caving descender. It can be used with 9 to 13 mm diameter low stretch kernmantle ropes (on one rope strand) or with 8 to 11 mm low stretch kernmantle ropes (on two strands) to facilitate long descents over 80 meters. The brake bars are replaceable to prolong its useful lifetime.

Suited for long descents (over 80 meters):
