The OK Screw Lock Carabiner by Petzl is a compact, lightweight, manual locking, symmetric carabiner. The easy to use Screw-Lock was designed for use with pulleys and hauling systems. The red band indicates when the 'biner is unlocked to keep you climbing confidently. This device is perfect for sport climbing or mountaineering in dirty environments where dust and dirt cause an automatic locking mechanism to malfunction. The pear shape facilitates use with the Munter hitch for single ropes. Try not to think about the pear shape too much, it might make you hungry.

FEATURES of the Petzl OK Screw-Lock Carabiner

  • Symmetric shape is ideal for use with belay devices to maximize efficiency no matter which end is closest to the device
  • Oval shape works great with pulleys
  • Keylock system
  • Available with manual locking system (Screw-Lock) or auto-locking system (Triact-Lock)

Rated 5 out of 5 by from Good Carabeaner, Could be better This carabineer is Awesome! It is a little bit heavy. Also it needs to have an identifying mark on it so that I can distinguish it from other similar biners. A green band that shows on the other side of the gate would be awesome. The reason is that when this biner is closed it looks identical to all my others (ones without the red band) which defeat the purpose of knowing that it’s closed from a quick visual check. Not a big deal but it would be a nice improvement.

Rated 5 out of 5 by from great for anchors Oval 'biners are the shape of choice for top rope anchors. They are called bottom rope anchors in England and the English are right. After all, you are belaying from the bottom, so bottom rope make more sense unless you are thinking anatomic bottom instead of geographic bottom. Anyway, having a locking carabiner in your setup adds more security. If you don't know what I am talking about, please stick to indoor climbing.

Rated 4 out of 5 by from Great Oval Biner, Alittle Heavy This is a great locking biner. It works well with the Triblocs, (I've seen other biners tear rope up) as well as with the legere pulleys. It's alittle heavy for weight conscious folks, but is worth the weight to use the legeres. I use these for Z Pulley systems during crevasse recovery, and they work flawlessly.

Rated 5 out of 5 by from The Anchor's Best Friend. I use this carabiner for my top-rope anchors along with the webbing as seen here:,,,,You can use two carabiners (locking or non), with the gates in reverse direction, for a safe redundancy.

Rated 5 out of 5 by from Excellent carabiner for gear This is my favorite carabiner to use with prusik tending pulleys. It has a really nice and smooth screwlock. It works fairly well in sandy and dirty conditions. A few quick snaps and it cleans itself out. The screwlock doesn't cease up when under load. Easily one of my favorite carabiners.

Rated 5 out of 5 by from Great Product! These Carabiner's are the best, i have three of them and would not trade them for any other. They are so light and easy to use, plus they are the strongest i have ever used plus i love the red stripe because if you see it you know you are not safe and need to screw it back up.

Rated 5 out of 5 by from great locking carabiner I use this with my grigri and it is awesome. i keeps the grigri straight and reduces the risks of cross loading much more than the petzl william (still a great carabiner) that i used to use. this is probably the most solid feeling carabiner i own.

Rated 5 out of 5 by from Good buy I use these if I'm running laps and lowering of anchors repeatedly hanging off a couple of 24cm Petzl dogbones or if I am setting toprope for buddies. They work great for pulleys and the like as well. Highly recommended.

I would like to buy some caribiners to temporarily hold a heavy chandelier from the ceiling of a pavilion at my daughter's wedding reception this summer. I don't want it to fall on the guests. Anyone have any thoughts on which caribiners would work best? 

Asked by: NightNurseJoy
Hey there, Thanks for reaching out to us! You bring up a good question...but a tricky one. So, carabiners are measured in kilonewtons (kN) which is a measurement of force. If you fall off a rock, you want the carabiner to be able to take the entire FORCE of you falling. To be technical, carabiners aren't designed to maintain weight, they're meant to bear force. However, with a simple conversion, you can see how much weight a carabiner can hold. This carabiner has 24 kN with the major axis (essentially, what you would use). One kN = 225 lbs. So you'd be good up to 5,400 lbs. If your chandelier is heavier than that...then that's a huge chandelier. Hope this helps you out!
