Description

Give yourself space to lock into your belay station with the Rocklock.

The Black Diamond Rocklock Twistlock carabiner is one of Black Diamond's largest locking biners. The new Keylock has a non-snagging keylock nose. A slightly curved spine maximizes the gate opening and a square hinge end holds your belay loop securely in place. The Rocklock's large size makes it an excellent choice when using two ropes, wearing gloves, or when using a variety of belaying and repelling techniques. Its large capacity can handle multiple clove hitches at belays. It's easily operated with one hand. –Vendor

Reliable

  • Familiarity: I've put it through the wringer

Good size for rapelling and belaying, light and strong.

Super useful biner!

  • Familiarity: I've used it several times

These are a great sized biner! Big enough to belay with, and they work great for building anchors on multi-pitch routes.

Round stock lets rope slide through effortlessly. I'll be sure to keep these in my rack as long as Black Diamond keeps making them

No Frills Winner

  • Familiarity: I've put it through the wringer

These are great biners for belay options. They're big, cheap, and strong. I use mine for belaying a second on multi pitch routes with a BD ATC Guide. The size makes it easy to clip into crowded anchor points and keeps my belay device far enough away from everything else to not get in the way.

Heavy duty lockers I use on every big wall. They're used as my Aider Ladder lockers, they provide a huge handle when leading an aid pitch, and serve as a great bener hanger at anchors. Great Screwgate Lockers!

My go-to

  • Familiarity: I've used it several times

Great carabiner! I love the screwgate, simple and easy to use when your hands are full. Just wish they offered it in more colors.

Hey David,

That's odd, the packaging when she got it listed the biner as a Rocklock. I'll have to compare it to one of my old Positrons next time we're out! Thanks for the heads up, I'll let ya know once I've put them side by side :)

Durable and Well made

  • Familiarity: I've used it several times

This is a great carabiner for all around use. The locking mechanism works well and makes it safer too use. I've used them a dozen times so far and the work great, I have bought more since my fist purchase.

Time tested.

  • Familiarity: I've put it through the wringer

You can get a fancy Magnetron or something for $30 if you're into it, or you can get the Rocklock for 1/3 of the price and have it work just as well.

Great Biner

  • Familiarity: I've put it through the wringer

The friend that got us into canyoneering recommended the Rocklock Carabiner. 7 years later it is still our go to Biner. It' s a no brainer as to what we are going to buy when our old ones wear out.

Cheap and reliable

Not the lightest carabiner, but its also not the smallest. Ample space to clip in and really easy to use with gloves on in the winter. The price is right.

Big, easy to use, pocket friendly.

  • Familiarity: I've used it several times

It is a big biner that is easy to use. It is pocket friendly. There is a reason you see a ton of them connected to a belay device. Unless you are an ounce counter or need to have the newest or most exspensive stuff, just buy it.

Good Big Biner

  • Familiarity: I've put it through the wringer

It is a nice size for a belay carabiner. I keep a figure 8 and an ATC guide on it and can still put a clove hitch on there while belaying. However, its not really any stronger than the much smaller and thinner positron locker. I would think that the beefier size would make it stronger. Must have something to do with the tensile strength of the aluminum regardless of thickness.

My goto Belay biner

  • Familiarity: I've put it through the wringer

Love this carabiner. Lots of room for any rope. Very trustworthy as a belay workhorse. Highly recommend.

Great heavy duty locker

  • Familiarity: I've put it through the wringer

These are great for Heavy duty work like Belaying, Top Roping anchors, etc.

Great for everything perfect at nothing

  • Familiarity: I've put it through the wringer

These biners are the standard. I use them for anchors, belays, whitewater taglines, live-bait rescue tethers, even carrying my keys when I have to retire one. Don't expect it to excel at anything, they weren't built for that. They were made to be the majority of lockers on your rack, not all of the lockers. They are great, inexpensive biners for setting up systems and no rack is complete without a dozen.

Beefy Locker

  • Familiarity: I've put it through the wringer

Big locking biner. Use them exclusively for top rope anchors due to how cumbersome they are. Would not use them for much else.

All Around Good Locker

  • Familiarity: I've put it through the wringer

If you are looking for an all around good locker then look no further. For the price this locker is fairly good. No complaints yet with it but then again I usually just use it for an anchor so I don't get to see it in action all that often.
