Last month DMM issued a recall on some of their locking carabiners.
The decision on the product recall was due to the small spring that sits against the body of the carabiner, the section that forms the push gate. It was felt that the fault may potentially prevent the gate from closing or prevent the gate from locking.
DMM have produced a Product recall list so that you can find the carabiners affected and how to inspect if you find that you have one of the recalled ranges.
DMM have apologised for the inconvenience caused and are looking to replace any faulty carabiners in the shortest time possible.
