Mad Rock Ultra Tech HMS Screw Carabiner

Pair Mad Rock's Ultra Tech HMS Screw Carabiner with the Ultra Techs that have black gates so you always know to use it for the anchor's rope instead of the bolts. Over time, bolts will ding carabiners to the point where they can actually harm your climbing rope's sheath, but the HMS will stay nice and smooth if you use it only for the rope.
