DMM made an announcement on the 11th of September regarding a safety issue with the gate action of a number of carabiner types. There is no recall action yet, but it is likely there will be and we will let you know what action to take as soon as there are any updates. *Even though Ultra-O carabiners are not on the list, we recommend you inspect the action of them too as we have witnessed the same issue in them before.
Below is from the DMM Statement, click here for the original PDF from DMM.
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.
In addition, the carabiners listed below with the following individual identification numbers:
Remove all affected carabiners from service.
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.
Sincerely, The DMM Team.
