The DMM Ultra O's symmetrical rope baskets are ideal for assisted breaking devices, pulleys, swivels and shackles. They also give stable loading characteristics, as attachments can self-centre under load with minimal movement from the carabiner. The Locksafe triple action model is a perfect companion to the the Hitch Climber and Pinto pulley ranges. The oval shape allows central positioning of devices. I-Beam section for increased strength to weight ratio. Keylock clean nose for snag free connection.
