Rated 5 out of 5 by from Excellent, Intuitive Design I made this purchase to add a little extra piece of mind while belaying my kids during their climbs. I use mine with the Black Diamond ATC Belay device: the belay loop on my harness stays securely in the small end of the carabiner (below the gate) and the large end leaves a great surface area for the belay device and rope. Additionally - which I am sure is no accident - the loop on the belay device cannot reach to the gate when the device is properly attached to the large end of the biner, so there is nothing to get tangled or in the way. Slightly lighter than most of the Black Diamond RockLock carabiners, and only "sacrifices" 2 kN in strength along the major axis (22 kN rating for this biner vs. 24 kN for the RockLocks). Easy to use, and no more cross-loading! Excellent carabiner. Strongly, strongly recommended.

Rated 4 out of 5 by from Great Belay Biner I really like this biner for belaying. I have been using this biner for several years and it is great for Belaying, no more cross loading while belaying. I use this with the Mammut Smart Alpine device and it is just big enough to accommodate the device and doesn't move around so I have piece of mind knowing that the device will function properly. I don't use it for anything else but belaying as it isn't as well suited for much else.

Rated 5 out of 5 by from Best belay biner around I just recently picked up the Gridlock Screwgate Carabiner and I am in love. It took a second to get used to the gate action to lock the belay loop on the bottom, but after a couple uses it is natural. I used to constantly have my Rocklock rotating while I belayed and it put my climber in some dangerous positions. I no longer have to worry about that and I can focus solely on my rope and climber.

Rated 5 out of 5 by from Great for belaying! Doesn't rotate like my other biner. Easy to use, light. Makes me feel a lot more confident in my belay, and reducing the chance of equipment failure.

What is the proper belaying orientation for this carabiner? Small end of the major axis to the belay loop and large end to the belay device? Or, the opposite?

Will this work with the Petzl Pirana?  My other locking carabiners are too large for it.

Asked by: dr3x
Yes, we did a fit test and the GridLock Belay Screwgate locking carabiner fits a Petzl Pirana descender device.
