    Comments about Black Diamond RockLock Screwgate:

    This biner works great for any belay device. I am a big fan of the screw lock and also there is plenty of room to easily feed the rope through on a belay or even a rappel. Great design and clips fast. Also sunny sports ships it to you in a hurry even with standard shipping!
