The Black Diamond Gridlock Screwgate Carabiner is a new hot forged belay biner that eliminates the possibility of cross-loading. The intuitive design is simple with no extra moving parts, just snap your belay loop into the smaller side of the "8", lock the gate, and you are good to go. The Gridlock screwgate also features an i-Beam spine that transitions into a rounded rope bearing surface. This Black Diamond carabiner is totally hot forged and weighs in at a teensy 76 grams.

Great carabiner for what its made for! Less convienient to take on and off.The Gridlock will not crossload on you! Guarenteed I have tried to force it to crossload and it just won't which is perfect because that's what it was made for. It is slightly less conveinient to take on and off because you have to situate the carabiner around your belay loop but considering my old carabiner was constantly cross loading its worth it. Also a heads up if you have an Alpine style harness ( I think that's what they are called. I'm talking about the ones that just have a crotch loop and you tie through that and your waist belt) it won't fit as designed. My buddy makes it work and I don't see a safety hazard with it but I really don't know so I wouldn't suggest it.

Excelent Biner to belay withBeen using this for a couple of weeks now and I really do like the way it feels to belay someone with it. I may offer more cons than pros but most of those cons are just my personal preference.,,,,Pros - Does not move at all when the "small" eye is in the belay loop. No chance of cross loading. Overall it just feels more secure in comparison to other biners. ,,,,Cons - Can get a little annoying to open the gate twice to remove/put on/hook up ATC. If you're clipping this on and off your belay loop A LOT its not nearly as convenient as regular biner. Dont recommend using "big" eye in belay loop.

Does Exactly What It's Made ForSay goodbye to crossloading! The gridlock is easy to put on (clip it on your belay loop, pull out, and "snap" it's on) and it takes only one extra step to remove. For the five extra seconds of work you will never have to worry about your biner turning on you mid-belay.,,As for the locking mechanism, a twist lock would add more weight and force you to unlock it multiple times when taking it on and off, the screw lock is perfect.,,My only gripe is the lack of a visual cue to see the gate is locked, but you shouldn't rely on those anyways, squeeze check and climb on.

Great Idea with one Draw BackThis biner really does preform well, keeping the crossloading to almost 0. The draw back is in the manucafturing of the gate spur. If you get your hands on one, run your finger on the bottom edge of the spur that keeps the biner from cross loading and you'll notice that the edge is quite sharp. Not razor sharp but a lot sharper than any other part of any biner I've seen and sharp enough to do some damage to your belay loop if you're not carefull. A couple loops of tape around the spur should keep your belay loop nick free and your leader very happy.

Beware not to unscrew it when the rope slides past it.I bought this locking carabiner as a lighter alternative to the DMM Belaymaster locking carabiner. I was also fed up when I lost the plastic protection of that carabiner.The Gridlock carabiner is good, because it prevents itself from turning around in the belay loop. But I have experienced that the lock can unscrew itself when the rope passes by.,,,,I should probably have bought the Black Diamond Magnetron GridLock Carabiner instead. Probably I was to conservative in the shop.

Not a necessity, but definitely a cheap luxury upgradeI had read previous reviews about people saying it's hard to figure out/use and takes longer to set up. But I'm here to tell you, I didn't major in rocket science at Harvard and I figured it out on my first try : ) As far as it taking longer to set up, yes, it does take one second longer. Though in the grand scheme of things, one second is well worth the added safety benefits. As far as it being a necessity? No, definitely not. But for an extra $10, it's added piece of mind!

Good Carabiner!I bought this carabiner when it first came out, and overall have been very happy with it! I really like the concept, but have often had to double check the positioning of the the ATC within the carabiner and with my harness loops. At times, if I get ready to belay too quickly the part of the carabiner with the little teeth will sometimes get caught on my harness loop and not close completely. This doesn't happen often, it's just something to be careful not to overlook!

Not necessary and not friendlyUsed this during work at a climbing gym with kids. They implemented this for extra safety. My experience from working there and coming across this after quite a lot of times is still bad. I couldn't get used to the extra work needed to pull the rope out of that "safety zone" before removing the biner. ,,,,I personally have lesser experiences of rope being crossloaded on a biner and thus I find this design rather ugly and unfriendly. Well, thats my take!
