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

A little on the bulky side when it comes to lockers, but super sturdy and functional. Can't complain.

Great big locker to put a belay device on or build anchors with. And the price is good too!

I love this biner! Great to have for rappeling. Wide enough to throw a munter on there. I prefer screw gates over twist gates. Cheap price, get a few!

I have a few of these and have absolutely no complaints. I use them anchors and belaying. They're everything you'd expect from a carabiner at a reasonable price.

For the price you will not find anything better. There are also many that the BD beats that are more expensive. Sturdy and have never seen one that has a bad action. One of the best lockers I have ever used.

This biner performs like any other climbing biner except it is very BIG so if you're ever cleaning a route and you drop your belay device, you can always throw a munter hitch on this biner with both strands of rope no problem. Problems solved!

The original! Probably not, since this is the updated version, but I've had this on my rack since day one! I only prefer the Petzl AM'D/ Attache if you're looking for the pear shape.

I have a handful of these that I use for everything from belay to anchors. I love the big size, it makes them super versatile and somehow they are still lightweight. You definitely need to have a handful of these in your kit.

I have a few of these twist lock biners. They work very well with the grigri 2; being fully rounded, this is something I liked as opposed to the vapor lock BD.

BD = Zero Issues
