Big Burly Beast

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

I Literally Own A Dozen

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.

Solid And Simple Carabiner

This carabiner just works. The gate opens wide and the screwgate feels secure every time. It’s a bit heavier than some other options but not a big deal. It holds up well without any fuss. Just a solid, dependable carabiner that does what it’s supposed to.

I Recently Received The Rocklock

I recently received the RockLock Screwgate Carabiner, and I’m thoroughly impressed. It’s a high-quality, well-forged piece of gear that offers exceptional versatility for activities like hiking, rock rappelling, and more. The standout feature is the safety-designed screw lock system, which provides extra peace of mind by preventing accidental openings during use. This makes it a reliable choice for any outdoor adventure. It's definitely deserving of a 5-star rating for both its craftsmanship and its focus on safety.

Still gets stuck on my Petzl Neox sometimes, otherwise still works good.
