Good locker for your ATC

This is a great biner for belaying and rappelling with an ATC. For most other purposes, you can get by with something smaller and lighter. Also makes a good biner for autoblock "guide mode" with an ATC Guide or similar device. Nice to have one, but rarely need more than one this size.

They’re good

I’ve had one get stuck in the locked position and had to get someone else open it. It hasn’t been a problem since but something to think about. I love the size of these better than it’s smaller counterpart.

We won't do anything without asking your permission first. These are your images, we just hope they can help future outdoor enthusiasts find the gear they need.
