Mammut: Possible Malfunction in Via Ferrata Set Safety Carabiners

If you purchased a bundle including a helmet and Via Ferrata Set, you only need to check the Via Ferrata Set and return it if necessary. All other products can be used safely.

Possible Fault

Two possible faults have been identified in the carabiner of the Skywalker Pro Via Ferrata Set safety equipment. The issues are particularly evident at low temperatures and may affect safety. The cause lies in the carabiner's plastic latches, which can slightly deform inwards due to external factors during production, transportation, or storage. Subsequent exposure to low temperatures may cause the latch to jam, restricting the carabiner's movement and preventing it from closing completely.

Check your Safety Equipment

The check applies to all Skywalker Pro & Pro Turn Via Ferrata carabiners without batch number 07/2021 or 11/2022.

To ensure safety, follow these steps:

  1. Check the batch number on the carabiner. If it is batch number 07/2021 or 11/2022 without an additional "R", you can skip the check and return the products.
  2. For other batch numbers: Place the safety equipment in a refrigerator at a temperature between 0°C and 10°C.
  3. Leave the equipment in the refrigerator for at least 1 hour.
  4. Remove the equipment and immediately check the carabiner by opening and closing it several times.

The carabiner may be defective if:

  • The carabiner sticks in the open position.

  • The carabiner opens and closes with difficulty, instead of moving smoothly.

Next Steps

If the safety equipment does not exhibit the above symptoms and the carabiner is not batch number 07/2021 or 11/2022, it can continue to be used safely.

If the safety equipment exhibits the described defects, immediately stop using it and follow the return procedure.
