When the gates on metal carabiners are opened or closed, are connected to metal anchor points or when they rattle against each other, they make a distinctive, non-natural noise. The DMM Ghost carabiner has been designed from the ground up to minimise this noise.
In the past this has been achieved by hot dipping the carabiner in plastic, but the temperatures involved in doing this risk altering the physical properties of the carabiner. Sniper tape has also been used, but this is temporary and neither method help reduce the metallic click when the gate hits the nose of the carabiner.
The aim of producing the Ghost carabiner, was to significantly reduce the sound signature of the gate mechanism and all other contact surfaces whilst maintaining the size, gate opening and strength characteristics of a standard screwgate carabiner.
By creating a bespoke, skeletonised carabiner back, we have been able to injection mould a noise reducing coating over all of the main surfaces whilst leaving an exposed aluminium rope basket to maintain good wear characteristics where the rope runs.
The unique screwgate mechanism contains proprietary dampers to manage the distinctive ‘click’ of the gate mechanism being opened or snapped closed, a feature which is especially important in covert urban climbing operations.
Another benefit to the over moulded screwgate barrel is that it creates an anti-vibrate function once fully closed that helps stop the barrel loosening accidently and so adding another level of safety.
Weighing 2.5oz (72g) and measuring 24.4 x 4.29in (62 x 109mm), the DMM Ghost is an excellent size for general purpose use and is certified to EN362:2004 A and EN12275:2013 B.
