The AustriAlpin Ferrata.Bloc can be combined as a "third arm" with any via ferrata set. Upwards it runs loosely on the wire rope, in the event of a fall on the vertical rope, it blocks in place. The brake arm prevents long falls until the next intermediate lock. The marking "this side up" shows the user at any time whether the brake arm is properly hung on the wire rope. With integrated shock absorber. The Ferrata.Bloc does not replace a via ferrata set. Please note the instruction manual (English language not guaranteed)
