Great carabiner for belaying
I bought this for my daughter to help her make sure that everything was set up correctly when she belays and I may end up getting another for myself since I end up belaying both of my daughters and my wife in quick succession when we are at the gym. The carabiner works well and does not rotate but takes a little more effort to get set up. It goes quickly with practice though. The screw lock is secure and easy to operate with one hand. Clip the carabiner to your harness, rig the belay device, clip the rope and device into the carabiner and then pull with the rope and belay device and everything snaps into place. Screw the lock down and you are set. Pretty dang easy.
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.
Good idea, but with some flaws.
Bought a couple of these for my wife and I to try out while off work, and they’re not as intuitive as I had initially hoped. While they are alright for their intended purpose, they do not make clipping in and out of the belay life loop as seamless as I would like it to be. The same goes for while it is clipped into the belay loop and I’m moving things in or out of the bell of the carabiner. Again, it works but I think it could be improved by somehow making the ‘hook’ or whatever you call the stem that separates the belay loop from anything else in the carabiner an independent part from the gate so that it doesn’t move or interfere with opening the gate.
more trouble than they’re worth
i bought this in a package with the ATC pilot. the pilot is great, but this beaner is over engineered and with the way lowering with the pilot works my rope has cut a fairly significant divot into the top of the major axis in only a few months. if i kept using it this beaner wouldn’t make it through 2 season. and because of the divot it no longer engages the auto locking on the pilot.
Just started using it
So far so good. I climb Solo and improvised. Everything helps. Does reduce the risk of cross loading and things getting out of posistion. I use an extended rappel device and tether with a regular screwgate. This gridlock screwgate sits on my belay loop for self belay and whatever else I can come up with. So far so good.
Get something different.
Picked this up as a belay beaner. I only use it for a backup prusic setup that rarely sees use. Because the harness loop gate is one piece with the carabiner gate, it's a bit of a maze to navigate the carabiner through rope, belay and harness. Ideally, you could clip all three items, then set it in your harness loop, but because the gate is one piece, you have to open the gate, pin the rope/belay in place so they don't slip out, use a spare hand you don't have to get the harness loop lined up and then close the gate. Not worth it. Get something else from somewhere else.
Prevents Cross Loading
Using my standard carabiner, I experienced a situation while belaying a partner. The climber was moving upwards at a good rate, I was pulling out slack, then took my partner’s weight on a rest. Something did not feel quite right, I looked down and observed my belay carabiner had cross loaded. I quickly remedied the situation. In the interest of safety for future adventures, I purchased the Black Diamond Gridlock Screwgate. Due to its design the device works well, and from my experience it eliminates a cross load. It was a good investment in safety, and I have purchased a second one for my partner.
Decent Belay Carabiner
I like that it has a mechanism to keep it in the right direction when belaying. But I find the Edelrid one to work better and this one is sometimes a bit of a pain. Some of the youtube reviews show some quasi-failure modes that don't inspire a lot of confidence either. Even so, those have to be rare and I've never had a problem. But it is a bit of a pain to get this on my belay loop and it has caused a little fraying as well.
solid Biner
Huge fan of this carabiner: I use it with a regular ATC and with an Edelrid Megajul. With both devices this works great! The screw gate is alright, about average, but where this shines is the belay loop section. It’s so intuitive to get the biner in the right orientation, and it’s a lot safer! It makes me a lot more confident in my belayer knowing there is one less thing that can go wrong.
Provides a great piece of mind
When I'm on belay, I like to feel confident. I like to know that I'm doing my best on not leaving things to chance. And that’s exactly what this carabiner helps me accomplish. Yes, I can use an HMS or any other carabiner. But by having that belay loop guard or lock. Depending on what you want to call it. I have a big piece of mind knowing that my carabiner will never get cross-loaded. I just don’t have to worry about it and all of my attention goes to what 's happening above me. So this is truly a belay only carabiner. Now, I have seen some people struggle at first with it. I even got some for free for some people that didn’t like it at all. But after I showed them how easy it is to set it up with minimum manipulation even though the gate belay loop guard and screw gate is just one piece, they decide to give it another try and in most cases they do change their mind about it. So, just keep that in mind when you are trying it out for the first time.
