Positive Reviews:

It's cool design but kind of a hassle. the reason why belay-biners typically get crossloaded is b/c there is a large amount of slack in the system and then the system is loaded again. If you're only top roping, this is an unnecessary hassle as there isn't that much slack in the system typically. if you're lead climbing, there is often more slack in the system and this is understandable. But when was the last time you had a Gri Gri cross-load? those guys are hard enough to move around on the carabiner to begin with! All aside, it's a pretty cool carabiner and I would recommend it to someone who was really concerned about cross-loading.

Great for its intended purpose.

I like this biner. My wife likes this biner. The gridlock does what it is designed to do and I'll leave it at that. There are certainly times that I chose a more traditional biner (like the RockLock). My wife likes her gridlock to much (particularly for multi-pitch or complicated anchor set ups because it gives her a warm-fuzzy that she's not going to side-load anyting). She's making me order two more for back ups in case we ever damage one. We use this in combination with our BD Mini Pearabiner and ATC Guide EVERY time we climb/multi-pitch.

Somehow I keep having partners leave their gridlock's with my gear--I've got so many now, I can't keep them straight anymore--it's a good thing I like this biner so much.
This biner does one thing and one thing only--keep you from crossloading your belay biner. I never use it on anchors or in any other setting--but for a belay biner, this thing is hands down--the best biner on the market. I figure every climber should own one--maybe two, just in case you decide to leave one in my pack.

Never leaves my harness

Whether ice or rock climbing, mountaineering, ski touring, the Gridlock never leaves my harness. Sure there are other biners designed to prevent cross loading, but for the first time, I own one of those biners that actually works. Next gen improvement: please increase the depth of the knurling on the gate (for those like me who use the Gridlock with gloves). Overall: It works in real life mountaineering, and simply for that reason, it's excellent. slickness and beautifull design are just bonuses.
Greg at Mountain Gear on 10/10/2013
I was having issues using a normal Carabiner with an ATC Guide and GRIGRI at times; cross load. So to be a better belayer and to be SAFE, I got this product. It's very lightweight and easy to use, but I found using a grigri the normal way could lead to cross load. To avoid this, I flipped the gridlock around so the grigri is in the narrow area. Other than that, it is a must have but wish it was auto-locked.
Where is Chris at on 03/07/2013

I've used it sport and top roping and it has been reliable and never had to worry about cross loading, particularly with slack in the line while leading.
It is specific to belaying and doesn't make a good multipurpose carabiner, but if you need one and only one belaying biner it is a great choice. Fits well with both ATC or grigri. I've had no problems with the screwgate. I would recommend it to any climber and always keep it with me.

I really like BD carabiners. This is no exception. I have used other locking biners for belay in the past. I just picked this up last season and have definitely noticed that it stays put and does away with twists and cross loading. Mostly notice when belaying a lead climber with an ATC. Does what it is designed to do.
I would recommend this to anyone looking for a belay biner. Match this with an ATC-XP or ATC-Guide for a great belay.

shaun Moyes at on 08/19/2013

Love this carabiner! Keeps you safe and looks good on your harness. Lots of people theses days don't know what cross loading is and its dangers. If you use this it prevents it from happening and personally i wouldn't use this for anything other that belaying! A little pricey but definitely worth it it in the long run! Had it for a year or two now and other than a few scratches it looks good as new!

Adam D. at on 08/13/2013

I use this with both my Grigri and my ATC-Guide and it works very well. It's a little awkward to rig up the first time or two, but I got used to that very quickly. An ATC can be used on either side, but a Grigri must be used on the small end. And since it's a Black Diamond, the screwgate is excellent. Well worth the investment!

This is one of the first Carabiners that I have owned and thus far it has been easy to use and my favorite. I have used regular carabiners and would choose this one over those. This one works well and the gate is large enough to be effective in multiple situations. Comfortable to use and grips well over standard carabiners.

Nice, but disappointed

Nicely designed, and innovative. However, I was disappointed that there was no "visual locked" indicater (the red ring that visually shows that the biner is locked). This would seem to be a no brainer when the primary use of this biner is for belaying. The absence makes it hard for the partner to visually confirm that the belayer has the biner fully locked. It is clearly made in china, as its fit and finish do not meet the usual BD standard.

This gate, does one thing and does it well, it's for that reason I'm not a big fan. As a belay gate is amazing! However, I prefer to have gates that are versatile. If you are happy with a gate that just belays this is the gate for you.
