The Croll chest ascender is unmatched for efficiency on fixed lines. Compact and lightweight, (30% lighter than the origianl Croll) it does not interfere with progression. The stainless steel wear plate improves durability by reinforcing the rope friction zone. The cam is stainless steel also.
  • Compact, lightweight chest rope clamp

  • Used with the ASCENSION handled rope clamp for ascending a rope

  • Toothed cam with self-cleaning slot optimizes performance under any conditions (e.g. rope that is icy, muddy, etc.). The stainless steel cam has better resistance to corrosion

  • The rope channel is reinforced with stainless steel for greater durability

  • Catch is opened by pinching for easy, simple manipulation

  • Lower hole is angled to keep the device flat

  • Upper hole for attaching a shoulder strap to keep the rope clamp in position

There has been some controversy over information on an Italian website.   Here is Petzl's offiicial response:.

Following the recent publication of 2013 CROLL tests on an Italian website (, Petzl would like to remind users of the following facts:

·  The new 2013 CROLL complies with the requirements of the EN567 standard when used with authorized ropes types (8-11mm). The CROLL withstands 5 consecutive static pulls of 4kN. During these tests the clamp was never pulled out.

·  We have tested the new 2013 CROLL with a large selection of ropes in slow pull static testing. The forces at which the sheath of the rope tore were: 5kN for the 8mm, 6-7 kN on the other diameters.

·  During product development and production, we have conducted many dynamic tests (shock load with a  rigid mass near an anchor point and extreme destructive tests with a guided mass on worn out ropes of large diameter) -- in these tests the clamp was never pulled out and the sheath of the rope was torn.

·  In normal use, the CROLL should never encounter such high forces, but it is critical that this (and all Petzl PPE) be used in accordance with the technical notice :

·  Petzl will contact the authors of these tests as soon as possible to exchange information.
