When you're a lead climber, you've got enough on your plate as is, building anchors, cleaning routs and generally keeping everyone on track and safe. That’s why we have devices like the Stubai HMS Pro Twistlock auto locking carabiner. Just clip the biner in and let go, it springs into a locking position every time. When you're continuously going on and off rope to change pitches or rearrange gear, a simple 90-degree twist unlocks the biner, making it a breeze to unclip one-handed even with gloves on. A brass lock slides like butter over the gate and the red anodized carabiner makes it easy to find on your rack and protects it from excessive wear.
