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.
