CPSC campaign 16164
Hazard
The Index Ascenders' rivet holding the toothed cam can release, allowing the Ascender to slide on the rope or become detached from the rope, posing a risk of injury or death to climbers from a fall.
Remedy
Consumers should immediately stop using the recalled ascenders and contact Black Diamond for instructions on inspecting and returning the product for a free replacement. Instructions for inspection are also available at https://warranty.bdel.com/IndexRecall/Landing. Only those ascenders having an unformed rivet need to be returned for replacement.
