Our revolutionary, patent-pending belay biner design that solves the orientation issue—never deal with a shifting, cross-loaded belay carabiner again. The GridLock’s isolation feature intuitively captures the belay loop and prevents cross-loading. Learn More


With its revolutionary, patent-pending design made possible by our 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.

GridLock Screwgate Carabiner is rated 4.6 out of 5 by 10.
Rated 3 out of 5 by from Good carabiner, but irritating anti-cross loading. I previously used a Grivel Clepsydra, but switched to this when I got a ATC Pilot. The slippage of the rope when locked seems to be roughly the same, but the Pilot catches less on the grid compared to the Clepsydra. However, the anti-cross load mechanism is irritating. Due to the construction, the gate has to be opened twice. If the lock instead would be an independent spring based mechanism, the biner would be much easier/efficient to use.

Rated 5 out of 5 by from Excellent (with a catch) Welp...3 months ago I hated this thing, liked the idea for marathon belaying at the gym with ATC so I never had to look down shamefully at my "upside down" pear carabiner, however found it to be a real pain to get over my wider BD Solution belay loop...I just got a BD zone harness (10/10 would recommend) and this thing pops right over its thinner belay loop, and now I love it!

Rated 5 out of 5 by from Never let your gri gri flip Keeps my gri gri in place safely love it! One less thing to worry about while belaying.

Rated 5 out of 5 by from Keeps it straight, and safe. A great and simple way to prevent crossloading carabiners. Pure and simple. Makes handling take and extra second or two, but it's worth it as I love my climbing partners.

Rated 4 out of 5 by from Solid belay biner Got this as a belay biner to use with my ATC guide and I love using them together. I've never had a cross loading issue or had to fiddle with the device. It's obviously more limited in uses than a conventional pear shaped biner (so you might have to carry others with you) but I think it's worth it for the ease of use.

Rated 5 out of 5 by from Love it, and has been improved since gen 1 So the photo on the site is the first generation GridLock. There was an inline change where the i-beam section at the top most bit where your rope runs is now a short bit of circular section. This is because the pure i-beam section would end up with some shallow grooves after using it for a while. Even with that small improvement I still love and use my first gen gridlock. I wouldn't recommend the Magneton version of it though for a belay biner. Leaving the gate unlocked makes it way easier to load it onto your belay loop, and load in your atc quickly. Rather than having to manipulate and unlock the gate multiple times moving it on and off your harness and belay device. Or having to do really intricate 2 hand movements to try to keep the gate open when taking things on and off. As say a via ferratta leash carabiner that'd be a really good application of the magnetron version.

Rated 5 out of 5 by from does it job Not much to say, solid biner, stops crossloading very well.

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.
