Black Diamond's PosiWire Quickdraw combines the Positron's snag-free carabiner for the bolt and a light HotWire carabiner for your climbing rope. The HotWire has an open-angled nose so you can clip your rope quickly, and the Positron has a keylock nose so the carabiner doesn't snag on bolts while cleaning. Black Diamond placed a StraightJacket retainer on the durable dogbone to stabilize the HotWire for even easier clipping.
