Fall arrest inertia reel block with energy dissapater system. Karabiner top connector and snap hook bottom.

The Blocfor™ 5 and Blocfor 6 ESD retractable fall arresters are equipped with an energy dissipater mounted at the end of the webbing. The dissipater ensures user impact in the event of a fall of less than 600 daN even when the webbing is fully unwound. The Extremity System Dissipater (ESD) reduces the dynamic load impacted on the user’s body in the event of a fall and protects the webbing from the risk of severing which could occur due to the sharp edges of terrace roofs.
