Petzl Basic

The Petzl Basic is a light and compact, multi-purpose ascender that can be used for a variety of rope ascents.

Offering excellent grip and working on single ropes from 8-11mm, the Petzl Basic is often carried by climbers and mountaineers for emergency use. Small and light it's a great versatile choice for rescue and hauling situations where a full handled ascender might be overkill.


  • Compact ascender with excellent grip
  • Can be used for rope ascent on a fixed line or as progress capture in a hauling system
  • Toothed cam with self-cleaning slot optimises performance under any conditions (e.g. frozen or dirty ropes)
  • Stainless steel cam has better resistance to corrosion
  • Lower attachment hole large enough for two carabiners (lanyard and foot loop)
  • Upper connection hole for guiding the rope
  • CE and UIAA certified

Rob Ward
Petzl Basic Ascendeur

I bought this not primarily for climbing, but climbing the mast of my boat - where weight isn't important, but security and cost are! I've been pleasantly surprised - the unit is lighter than I expected, so I probably will use it crossing glaciers in the Alps, it's beautifully engineered and really, unless you're intending to jug your way up El Cap, it seems a perfectly good, decently priced ascendeur that will work in any number of environments.
