The DMM Ultra O Coloured 3-Pack includes three different coloursof the Ultra O screwgate carabiners.
The DMM Ultra O Screwgate is an extremely symmetrical oval climbing carabiner, ideal for use with assisted belay devices, pulleys, swivels and shackles. Some oval carabiners are not as symmetrical as others, making them less useful for their designed purpose.
The DMM Ultra O is one of the most oval shaped biners available and performs particularly well in a 'big wall' environment, and any other situations where the carabiner needs to allow the attachment points to be centralised and hang straight.
Oval shaped locking biner for rigging stability and central positioning of attachments
