Our innovative belay biner featuring Magnetron Technology, which uses magnets in the gate and a steel insert in the nose for unprecedented security and ease of use. Learn More


Combining maximum security and ease of use like never before, the Black Diamond Magnetron GridLock uses the power of magnets to reinvent the auto-locking carabiner. Magnetron Technology uses two magnetic arms in the gate and a steel insert in the carabiner's keylock nose to create an ultra-secure, self-clearing and redundant locking mechanism that can be easily used with either hand. Combine that with our innovative GridLock shape, which traps the belay loop to eliminate cross-loading, and the Magnetron GridLock is the ultimate belay carabiner.

  • Hot-forged construction
  • Innovative gate design uses two magnetic arms in the gate and a steel insert in the nose for super-secure, interference-free closure
  • Keylock nose prevents snagging
  • One-hand operable
  • Unique shape isolates belay loop to eliminate cross-loading
  • I-Beam spine transitions into a rounded, large rope-bearing surface


Never deal with a shifting, cross-loaded belay carabiner again. The hot-forged GridLock’s radical design has an isolation feature that intuitively captures the belay loop and prevents cross-loading.

Rated 4.7 out of 5 by 12 reviewers.
Rated 4 out of 5 by Good for everything except beach climbing I like this a lot for it's safety. It's slightly harder to use 1 handed. I had issues climbing in Malibu on the beach with sand grains getting in it and making it difficult to open or close. Otherwise, I love it. July 8, 2015
Rated 3 out of 5 by A little less than what I hoped for 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. April 27, 2015
Rated 5 out of 5 by The best for rope ascension and belays 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.

Rated 5 out of 5 by Overall: exccellant 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. November 14, 2014
Rated 5 out of 5 by Excellent Edition 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. July 21, 2014
Rated 5 out of 5 by One of the safest out there, IMO 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.

Rated 4 out of 5 by Found a weakness Took on daytrip down Spry Canyon, Zion, 12 raps over the course of the day. Fine sand in the canyon caused 2 problems: 1. locking mechanism would stick shut requiring me to de-glove to use my thumbnail to pry open 2. sandy rope (unavoidable in slot canyons) burned a groove about 1/3 the overall thickness of the beaner I haven't had problems inside or on clean rock/face climbing and in that environment are awesome, hence warrenting the 4/5 rating still, but I was a bit bummed how poorly it performed for technical canyoneering.

Rated 5 out of 5 by Excellent, no fuss carabiner 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 October 30, 2013
