REGULATIONS

EN 12841-B (Rope adjustment devices for ascent): This standard regulates chest or fist blockers specifically designed for professional height work and access via ropes. Its main function is to allow the operator to ascend a rope efficiently and safely, automatically locking under load to prevent any involuntary sliding downwards.

EN 567 (Climbing blockers): This European regulation defines the technical requirements for blockers used in climbing, mountaineering, and technical rescue activities. Unlike purely industrial equipment, devices under EN 567 are optimized to offer a perfect balance between lightness and strength, facilitating progress on ropes of different diameters in mountain environments.
