Precautionary recall - Elastic lenyard

Mammut recalls the 2012 Via Ferrata Sets Tec Step Bionic, Tec Step Classic, Tec Step Brenta Classic and Tec Step Bionic Turn from the market as a precaution.

In August 2012, there was a fatal accident involving a Via Ferrata set from a competitor brand. As an immediate response, different testing institutes tested Via Ferrata sets according to tightened protection goals. These tests established that some karabiner arms made from elasticated webbings were far too weak – these products have already been recalled in summer.

The Mammut sets that were tested verifiable showed much higher breaking strengths. There was no immediate danger to users as the Mammut products using this elastic arm construction were only introduced in Spring 2012.

Meanwhile, Mammut executed further tests and investigations and these showed that there is a very small residual safety risk after very long periods of very heavy usage over several seasons. The risk to safety only occurs if the product usage vastly exceeds the recommended usable lifetime (see table).

In order to prevent any future risk to consumers, Mammut has decided to recall the following products as a precaution:

2130-00240 Tec Step Bionic

2130-00220 Tec Step Classic

2130-00250 Tec Step Brenta Classic

2130-00230 Tec Step Bionic Turn

The products affected by this recall are detailed at the side of this document. If you are in possession of one of the affected Via Ferrata Sets, you have the opportunity to send these back to have the elasticated karabiner arms replaced. The webbing will be replaced with a construction that increases the security and eliminates the residual risk described above.

The following possibilities exist for the return of the products
