Features 5

  • EFFICIENT ASCENTS: The benchmark chest ascender designed for rope ascents; keeps the body upright and allows for a smooth glide up the rope.
  • WIDE CHANNEL (Large Version): The CROLL L (B016AA00) features a wider rope groove that limits friction, making it ideal for use with wide-diameter (8-13 mm), swollen, or stiff ropes.
  • DURABLE DESIGN: Both versions feature a stainless steel wear plate (or reinforced channel) to improve durability against rope friction.
  • RELIABLE GRIP: The toothed cam with a self-cleaning slot optimizes performance under difficult conditions, such as frozen or muddy ropes.

High quality with unbelievable convenience.
Size: Small (8-11 mm)
It is hard to beat the quality of most any Petzl product, and this is no exception. Now top that with the shopping ease and quick delivery to my door of Amazon, just makes that much better!

Good for a knee ascension system.
Size: One Size
Great tool. It advances beautifully on the rope. The springs aren’t so tight that they won’t open the cam for advancement or too loose that they won’t grab. I rigged it into a knee ascender for rope walking and it is absolutely fantastic. It is easy to clip on your line and just as easy to disengage for removal. ... show more

Good ascender
I don't have much to compare it to, as this is the only chest ascender I've used. It feeds smoothly and grips well. I like that the carabiner holes are large enough to slide the gate of a locker through. My only gripe is that it's a little tricky to remove from the rope. The black lever could be a little easier to grip. I tend to grab it to take it off, slide it up the rope a little, and then the lever slips out of my hand and bites the rope again. It's not a big deal once you get used to it, but it's a little awkward at first. I never had this problem with the Petzl hand ascenders. Other than that it's a great product. ... show more

Great chest ascender for 8-11mm rope
Size: Small (8-11 mm)
This is for 8-11mm rope. It’s easy to use and setup on a chest and waist harness with locking carabiners. It’s smooth and grips my 8mm rope VERY well. It’s good to note that a chest ascender should be used in conjunction with another ascender (hand or foot). One little thing I’d like added is a bit bigger thumb release lever, but it does it’s job really well. ... show more

Great product
I have used this croll several times already. I have absolutely no complaints. Petzl makes great products anyway and I feel confident trusting my life with this ascender. It's smooth on the climbs, grabs quickly and doesn't slip. I have used this in Rusty's Cave and Cemetery pit in Fox mountain, and Case cave in Cloudland Canyon, as well as several practice climbs at various heights. I would recommend this product to anyone. ... show more
