"Simple, clean, reliable carabiner, great product and great customer service!"
"Great pear-shaped locking carabiner. Highly recommend."
"The RockLock is a great little carabiner, lightweight and versatile in its shape and size. The rounded profiles are gentle on ropes, and pulling them through is smooth. And there's something about a screwgate that feels a little more reassuring than a spring lock. I'm super happy with my BD carabiners!"
"Perfect HMS carabiner"
"A solid HMS I use it to rack my cams keeps everything neat and tidy, always ready if I need a locker for a munter"
"Great size and shape. Unless I'm trying to shave down weight for alpine multi-pitch, I'm always belaying with this. Wide basket, key lock nose, easy screw gate. In fact, the first carabineer I ever bought was a rock lock from BD and it's still kicking strong and looking as good as ever."
"This is the one you want for the stuff you need secure. The classic locking carabiner. Great product."
"Big fan of this one"
"Lightweight and buttery smooth. This Carabiner has a nice size for belaying and for masterpoint. well made and strong!"
"Been using these johns for years, they’re tried and true"
