The BACK-UP is a fall arrester for a flexible anchor line developed for work at height fall protection systems. Ideal for systems using a 10.5mm or 11mm EN1891 type A line. Employing a toothless mechanism to reduce possible damage to the rope, this device is one of the least aggressive on the market for textile ropes . Supplied with an OVALONE CARBON connector, it can even be used without a lanyard or energy absorber. It features a selector lever that allows you to choose between two modes of use: free sliding along the rope in both directions upward sliding only, which allows the user to reduce the fall factor. It may also be used as an ascender or as a rope clamp for rescue systems. Supplied with an OVALONE CARBON ANSI connector, this version also complies with ANSI Z359.15. A special lanyard with fall indicator is also included in the package. High quality, made in Italy!
