Product Description


The DMM Ultra O is a triple action locking gate karabiner, giving the user confidence and security as the triple action gate prevents accidental opening of the karabiner. The Ultra's oval shape allows for central positioning of devices and makes it perfect for use with pulleys and as a general connector. The I-Beam construction of the Ultra O increases the strength to weight ratio meaning it weighs only 73g but has a strength rating of 25kN. Constructed using hot forged and fully heat treated aluminium with an anodised finish to help protect it from corrosion and prolong its service life. Each karabiner is individually marked, allowing for easy traceability and testing.
