Petzl Footcord Ascender Foot Strap

Petzl Footcord Ascender Foot Strap


The Petzl Footcord is a lightweight, compact, and easily adjustable foot ascender strap which can be girth-hitched directly to your ascender or used with a carabiner or quick link. The Footcord is a more compact foot loop, as it is primarily cord with a reinforced webbing step. Adjustment of the Footcord is provide through a a tiny plate through which the cord passes. Pull through more or less cord to adjust the overall length of the strap to fit the tree climber. Cutting out bulky buckles and webbing let's this cord easily stuff into a pocket or pouch and brings the weight down to only 45 grams (1.6 oz). Petzl has really done a good job on this on - the minimal design and easy adjustment will make this a favorite for long SRT climbs.
