Petzl Croll Chest Ascender


Add Protect+ Powered by Extend™

Croll Chest Ascender

When it comes to ascending fixed lines, nothing rivals the Petzl Croll Chest Ascender for speed and efficiency. When used in conjunction with a chest strap (Petzl Torse) and a basic handled ascender, the Croll simply slides up the rope as you make upward progress. The self-cleaning slot allows the stainless steel cam to perform on frozen or dirty ropes, and the compact nylon trigger allows for quick manipulation of the device.

  • Toothed cam utilizes a self-cleaning slot so it will perform on dirty or frozen ropes
  • Stainless steel cam and wear plate provide durable corrosion resistance
  • Simply pinch the nylon trigger to open the catch and manipulate the ascender
  • Bottom hole is angled to keep the ascender parallel with the rope
  • Top hole is designed to attach a chest harness or Torse strap (harness/strap sold separately) to keep the ascender in the proper position
  • Designed for use with single ropes between 8 and 11mm
  • Item #PTZ0354

*BE AWARE* This is a CROLL S

I've put it through the wringer
Runs small

I was perusing here in search of deals and randomly saw this Croll. The item description is a little confusing and if not read fully, you may end up getting this item that is in fact a CROLL S (8-11). I have a Croll S, and it is great for caving, though it can have trouble feeding dirty or swollen rope. Just want to make sure people know this listing is for a Croll S.

Great self belay device

I've put it through the wringer

I mostly rock climb and dry tool solo top rope in Great Falls, VA. I needed a backup self belay device to my Petzl Micro Traxion. The Petzl Croll is perfect. Mated with a chest harness, I've put the Croll though the ringer and it has performed superbly. The device is everything you would expect from Petzl: Well made, durable, and solid enough to trust your life with. The video shows how the Petzl Croll and Micro Traxion protect you from falling. I think my ice axes gave way three times on this climb. Oveall a really great piece of equipment.

These guys are bomb proof and phenomenal for caving. That being said, pay attention to your gear and know when it's time for a replacement.

Iconic Ascender

I've used it several times

This device is exactly what you expect it to be, hardy, well made, and ideal for frogging. I use this to ascend rope out of pits and caves where it sees LOTS of dirt and nasty rope. The self cleaning teeth allow you keep right on moving up wet muddy rope. I would recommend this device for anyone looking for a chest ascender.

Best Chest Ascender Out There

I've put it through the wringer

This is an ultra lightweight and durable piece of equipment that's integral to my vertical rig (I climb on a frog system). Despite scraping it on rocks and dragging it through mud while crawling/climbing/etc from one pit to another, it's held up wonderfully and works as well as it did when I first bought it. If you're putting together a vertical system, I recommend buying a Petzl kroll instead of a knock-off brand. I've heard some stories about excessively-used krolls developing a sharp edge after years of use and severing rope sheaths so, as always, check your vertical gear before you starting climbing rope to avoid an accident.
