A biner with a twist of awesomeness.

From short sport routes to long hauls, climbers dig the easy twist-lock of the DMM Zodiac I Beam Keylock Carabiner. The mechanism is solid and never feels loose or rattle-y. And with 32kN of major axis strength, you can rest assured that your setup is bombproof (well, the biner part is ... double-check everything else, of course). To boost burly points, DMM fully anodized this carabiner for corrosion-resistance too.

Sturdy, light, bomber

Belay, top, bottom, rescue anchors. You will need a couple extra lockers for the trad rack. Solid and lightweight, a welcome complement.

What's the difference between quick lock...

What's the difference between quick lock and lock safe? right now I only use screw gates

Best Answer

The quick lock can be opened with just a twisting motion, but you have to pull the sheath up and then twist to open the lock safe.

Personally I'm a fan of good old screw gates. Or maybe I'm just a starving college student.


My Go To Biner

    I have a few screw gates but haven't used them since getting the Locksafe version. And I won't go back.

    This is a Definite buy.


    Pretty Nice

      Most locking biners these days aren't much stronger than a quickdraw, but I'm old fashioned and feel quite reassured by the 32kn rating. I also like that they're a decent size. They are pretty light for the strength and beautifully made. The screwgate is smooth and much tighter than my BDs - which rattles a bit. I carry a lot of old DMM gear that still in great nick and it's always been a joy to use.


      Great With Gloves

        I bought two of these with the twist lock gate and they are sweet! These are my first auto locking carabiners and they make me wish I had forked out the extra cash earlier. I bought them to try and make roping up with gloves on easier. Rope goes in and out easily, great product that simply works.
