    The reinvention of the auto-locking carabiner has arrived. The Black Diamond Magnetron GridLock Belay locking carabiner uses magnets for secure locking and unparalleled ease of use.

    • With magnetic arms in the gate and a steel insert in the nose rather than a twistlock or screwlock, the Magnetron 'biner is simple to operate and totally secure
    • Both magnetic arms must be individually depressed before the gate can open, to prevent accidental openings
    • Once open, opposing magnetic fields repel the arms to ensure smooth and reliable gate operation
    • Symmetric design lets you open the gate easily with just 1 hand, either your right or left
    • GridLock design features an extension at the bottom of the gate to keep the 'biner properly oriented on your belay loop to avoid cross loading
    • I-beam spine transitions into a rounded rope-bearing surface for smooth belaying and rappelling
    • Hot-forging process allows the metal to be moved around and formed into intricate shapes; these shapes can ease handling and reduce weight
    • Black Diamond Magnetron GridLock Belay locking carabiner has a key lock nose that won't snag on pro, ropes or slings, making the 'biner simple to clip
    • Magnetic arms on the gate come in assorted colors only; sorry, specific color requests cannot be accommodated

    Please note: Black Diamond products can only be shipped to U.S. addresses.

    Black Diamond Magnetron GridLock Belay Locking Carabineris rated3.0out of5by2.
    Rated2out of5byfromNot the best combinationI like both the features of this carabiner: the Magnetron auto-lock mechanism and the gridlock internal gate. However, they don't work well together. The Magnetron is eager to close and not super easy to open (generally a good thing for a locking mechanism!). The Gridlock requires you to open the gate several times: Once to get your belay loop into the main chamber Again to get your belay loop into the keeper chamber Again to get your belay device into the main chamber (Possibly again to get the rope in, if you didn't pre-load the belay device with the rope). That's a big hassle. It's not too bad for top-roping since once you get set up you only have to repeat the last step to get on or off the rope. But for multi-pitch, where the belay device is coming on and off your harness several times, it becomes a time suck. If I could purchase again I would choose the screw-lock version since that's very easy to open the gate multiple times while unlocked.

    Rated4out of5byfromGreat belay carabinerI'm actually a bit surprised I own this carabiner. First, I'm not usually an early adopter. Second, if something is a bit too clever, I'm usually turned right off. It happened that I wanted a Gridlock, and the Magnetron line had just come out. The Gridlock format is great; it keeps the carabiner in a known orientation on your belay loop, and you can be certain it's not cross-loaded. It takes a bit of fiddling to get it on and off, but you can do it in one motion with some practice. It's worth it. The Magnetron part is nice, too. The independent magnetic catches engage smoothly and positively, and Black Diamond are accurate in their claim that the magnets experience their greatest force (i.e., are hardest to open) in the gate-closed position. One thing I had to get away from was the idea that the gate had to support a significant compression (opening) force; the point of a locking biner is not to open inappropriately. I do not see this carabiner coming open by accident under normal circumstances. My one complaint would be around finish. There are some sharp-ish edges, all on the gate. The retainer section of the gate that sits on your belay loop has sharp edges near the pivot point. As well, the edges around the release buttons could do with some smoothing. Overall: this is a great piece of kit! Thanks, BD!
