DMM have released the following important safety warning:
It has come to our attention that the locking mechanisms of some DMM locking carabiners are developing a dysfunction. In a small percentage of carabiners, the interaction between the internal coil spring (which gives the gate it’s closing action) and the spring pusher (the component that holds the spring against the carabiner body) may cause the spring pusher to displace, potentially preventing the gate from closing or the mechanism from locking completely. This has raised obvious safety concerns, and we are taking this step to ensure the safety of the users of DMM carabiners. This only affects certain batches of the carabiners listed below:
In addition, the carabiners listed below with the following individual identification numbers:
• Remove all affected carabiners from service.
• Safely quarantine.
• Notify other users of DMM equipment.
• Await further instructions from DMM.
As of today, 11th Sept 2015, it is our belief that we will be commencing a recall of the affected batches next week. We aim to have a progress report and an action plan in place by the end of next week – Friday the 18th Sept 2015. Please monitor the DMM website, the DMM Twitter feeds and the DMM Facebook pages for further updates. We apologise for the inconvenience and endeavour to deal with this matter as efficiently as possible.
