Black Diamond's classic Quicksilver Screw-gate is a great value in a locking utility biner. It’s small, light and versatile for setting up belays, top-rope anchors or securing a haul line to your harness.

Large but light, the Airlock Screwgate Carabiner by Black Diamond is designed to work smoothly with any belay system, whether it’s an ATC, Super 8 or Munter hitch. A large internal volume holds all the bulky knots, harness webbing and stacks of runners you could ever need.

With a keylock nose that prevents the Black Diamond Positron Screwgate from snagging on bolt hangers or gear, this biner is ultra-easy to clip and clean. A perfect balance in size and weight, the Positron is ideal for hauling, rigging or top-roping. The Positron is a great utility biner offering good performance and durability.

The Black Diamond Axe Protector is a quickly adjustable translucent TPU protector for ice axe heads.  Fit almost any ice tool on the market with these, and protect yourself.
