Black Diamond connected a hot-forged Nitron straight-gate biner and a hot-forged HotWire carabiner to create the light, versatile and smooth clipping Black Diamond HotWire Quickdraw. The snag-free keylock Nitron takes the hassle out of cleaning routes, and the HotWire's large rope-bearing surface and flat gate-to-rope interface make for smooth clipping in any climbing application. The light, durable 14 mm Dynex™ dogbone also features a Straitjacket insert to keep the bottom biner in the optimal clipping position.
