Introducing the CROLL chest rope blocker, a key piece of equipment for comfortable and efficient rope ascents. Designed to guarantee ease of use and high safety, the CROLL boasts a moulded belay that is fully integrated into the body of the blocker to prevent accidental entrapment.

Two versions of the blocker are optimised for different rope diameters, each offering a robust, stainless steel cam with self-cleaning grooves for trouble-free performance in demanding conditions. Combine the CROLL with the ASCENSION manual rope blocker for the ultimate rope system.

1. The molded lock and fully integrated latch minimize the risk of accidental entrapment and make the blocker quick and easy to use.
2. The self-cleaning cam with spikes ensures reliable performance of the blocker on frozen or muddy ropes.
3. Stainless steel cam and reinforced rope groove provide exceptional resistance to wear and corrosion.
