Product description
The Black Diamond Magnetron RockLock carabiner uses a truly revolutionary gate that locks shut with magnetic tabs instead of a traditional screw gate. The advantages? Nothing to freeze shut in the winter or to clog up with sand, and you can operate the gate with one hand. Not to mention that this gate is significantly faster to open then traditional locking mechanisms. To top it all off, Black Diamond gave the RockLock carabiner a keylock nose that won't snag on gear, slings, or bolts when you tear down your anchor to head up the next pitch. Note: the locking mechanism comes in different colors (dark blue, light blue, green, or orange), so you might not get the blue that's pictured.

  • Revolutionary magnetic locking gate features two magnetized arms that repel each other when the gate is open but lock shut when they come in contact with the steel insert in the carabiner's nose
  • Gate opens by depressing the two arms with thumb and forefinger; can be operated with one hand, and design works equally well for right- and left-handers
  • Slightly curved spine maximizes gate opening
  • Magnetic gate doesn't have components that can freeze shut or clog with sand
  • Keylock nose helps prevent your rope from snagging
  • Hot-forged for maximum durability
  • Note: locking mechanism comes in different colors on the carabiner, so you might not get the blue that is pictured
