The Gridlock Screwgate by Black Diamond is a belay-specific carabiner. With its revolutionary, patent-pending design made possible by Black Diamond's in-house hot forge, the Black Diamond GridLock Screwgate eliminates the dangers of cross loading. Designed specifically for belaying, the intuitive, easy-to-use GridLock isolates the belay loop behind its uniquely shaped gate, thereby keeping the carabiner in its proper orientation. The GridLock's I-beam spine transitions into a large, rounded rope-bearing surface for maximum strength and smooth rope feeding. Simply put, you'll never have to deal with a shifting, cross-loaded belay carabiner again.

I look at normal carabiners as the weak link in the climbing chain because of the possibility of cross loading. At one point I even went so far as to use a steel biner with a 53kn rating until I found out it had the same 7kn cross loaded strength. Then I started wrapping surveyor tape around the biner and belay loop to keep it oriented properly, etc. THANK YOU MANUFACTURERS FOR FINALLY ADDRESSING CROSSLOADING! Do I think the gridlock is perfect? Not yet, but I also don't have any opinion on how to improve the design to perfection. The little tail can get caught on stuff and make the gate difficult to open or close. Also, it is very important that you check the location of the belay loop when you lock the gate just to make sure it is in the small eyelet portion of the biner before belaying, EVERY TIME. It is possible that the gate tail could lever the belay loop into the main carabiner opening creating a guaranteed crossload scenario. A super easy check but worth doing every time with this biner (see video.) Don't take this above criticism as a reason not to purchase the gridlock. I will be buying more here soon as I think they are great! You can check belay loop location, you can't check crossloading. I actually don't want anyone belaying me without one. Check this youtube link for a short video I made describing this. http://youtu.be/nrDpjH8YgIM

I bought this caribiner because I got tired of my RockLock's tendency to crossload, and because I wanted a belay setup that I could trust an inexperienced climber with. The GridLock solves both of those problems beautifully; however, in practice, the actual operation was far less elegant than I had hoped. When the gate opens it leaves very little clearance for the rope, to the point where if I'm doing a double-rope rappel, it's honestly a bit of a pain to get the thing in and out. I'm glad I have this piece of gear and love the extra safety, but if I could go back, I probably would have bought the VaporLock or the RockLock for the extra versatility.

stays in place, never crossloads

By Todd

from Rangely, CO 81648, USA

Comments about Black Diamond Gridlock Screwgate:

I use these to belay, for my young daugheters to belay each other, and for ascending ropes. They never rotate and cross load with an elegant design over the others out there. Only fault is that the bottom loop is too small to use on an alpine bod harnesses two loops. Better for wet ice climbing than the magnatron version.

The best for rope ascension and belays

By Todd

from Rangely, CO 81648, USA

Comments about Black Diamond Gridlock Screwgate:

In jumaring up lines in caves, etc I have always had issues with my waist carabiner rotating while unweighted and moving up the rope, and then catching and crossloading. I had to try this as soon as I saw it and it answered all my wishes. Great for stability during rope ascents, and I love it for belaying too. My only gripe is it doesn't have a large enough bottom loop to work well on my BD alpine bod harness. For beginners to belaying etc, I also love this as it eases my mind with its lack of crossloading potential. My young daughters exclusively use this on their harness when I take them out.

Comments about Black Diamond Gridlock Screwgate:

Working at a rock gym I use it quite often and it has been great. I do not have to worry about it cross loading or coming unscrewed ever.

A Simple, Elegant Solution

By Josh

from Canada

Comments about Black Diamond Gridlock Screwgate:

Love love love this carabiner. It fits well in the hand, is simple to use, while giving peace of mind that the biner will stay where it should, when it should. I would like it if BD make a larger version as well for other uses than belay.

Excellent Edition

By Levi

from Yosemite National Park, Yosemite Village, CA 95389, USA

Comments about Black Diamond Gridlock Screwgate:

Recently picked up this to update an old locker and fell in love with it. I have had my gate come unlocked multiple times while belaying and now I don't have to worry about it. The magnets seem very solid and the whole piece of equipment is very well done. I'll be burning up my other lockers on rappels for an excuse to move my collection to magnetrons.

One of the safest out there, IMO

By Anson

from Provo, UT

Comments about Black Diamond Gridlock Screwgate:

Just ordered this the other week and I can't say how much I love it. No biner is foolproof, now but I'm a lot less worried about a rookie belayer cross-loading the biner or forgetting to lock the gate - if it's closed, it's locked. It's easy to use with one hand. For one of the most frequently used pieces of gear, it's totally worth the price. I can't believe I bothered with screwgates for so long. From now on, all my lockers are going to be Magnetron.

One less thing to think about

By Steve

from Vermont, USA

Comments about Black Diamond Gridlock Screwgate:

I purchased the gridlock when it first came on the scene. It's a pretty genius little biner. I have never been terribly worried about cross loading a biner, but I always use the Gridlock now. One less thing to worry about, more time to focus on climbing.

Excellent, no fuss carabiner

By Eric

from Undisclosed

Comments about Black Diamond Gridlock Screwgate:

I was looking for something to get away from double locking spring loaded biners. This delivered. I was a little suspicious because it's so different and looked too easy to use online. Truth is, it is easy to use. It's also very safe as far as I can tell. If your hesitant on getting one, don't be... it's well worth it
