Technical guide for the CAPTO™ 11mm blocker-descender by CMC: dual ascent/descent function, CNC aluminium, EN 12841 & NFPA 1983 certified. Available at EASTAV, official CMC distributor in Spain.

As the official CMC distributor in Spain, EASTAV presents the complete technical guide for the CAPTO™ 11mm blocker-descender: a 4-in-1 device combining a V-slot cam blocker, high-efficiency pulley (91%), anchor point (becket), and progress capture.

Compatible with 11mm EN 1891 Type A ropes, its housing rotates 360° frictionlessly to always orient towards the load — critical at edges and in confined spaces. CNC-machined aluminium body, certified to EN 12841:2006 A/B and NFPA 1983 (2017) Technical Use.

This video demonstrates the main uses: assisted ascent, controlled descent, mechanical advantage systems (3:1 to 5:1), and technical rescue applications. Ideal for IRATA technicians, GWO teams, and industrial rescue professionals.
