Climbing TechnologyRollnLock Pulley, Orange, One Size

Paired with a carboner with a pully this thing is amazing. Good quality and very functional. Absolute game changer

This thing is like the leatherman wave of vertical accessories. It's too small and versatile to be the perfect tool for any specific task, but it's so small and versatile that I end up using it more than I'd like to admit.It's never the first thing I think of when I plan a setup on the ground, but I find myself turning to this tiny monster for many quick tasks when I'm already up there. It's really too small to handle comfortably, and it's definitely not a one handed tool, and it's not secured to anything while you handle it so you need to be extra careful, and It's just generally annoying to fiddle with if you're in a hurry, but it's always there because it's very light and useful, and it can almost always do the job.It's the same love hate relationship I had with the wave for the first 5 years I was using it, until I learned to appreciate it for what it was. They're both not the best at anything but they are always around and they will get things done.

Using this as a work positioning device in rope access. Can also quickly set up a 3:1 to ascend. Pretty happy with it.

Well-built piece that operates smoothly and is useful for so many climbing and hauling applications.

Great product. I love it's size, and versatility. Less cumbersome compared to the Petzl Traxion. Over all a great buy for the price.Loss of one star has to do with is operational performance. When used as a pulley on a fixed point. You need to make sure you are pulling strait down. You need to use an oval or a pear ring style carabiner. If you use a D shaped carabiner, the rollnlock will sit at an angel when under load, causing your rope to jump slightly out of the sheave( pulley wheel). If you have the cleat in an 'bite' position, this can cause your rope to pull the cleat around and can lock the cleat in the open position.You also can not side load the the rollnlock, or else the above will occur.It is also difficult to release the cleat from the open position when under load. Even if you quickly take the load off with one hand, trying to release the cleat so it can grab the rope can be difficult.Due to it's width. On D and Pear shaped carabiners, you can not pass the RollnLock to the opposing side of your carabiner. So on a pulley position like shown in the photo. If you need to relocate frequently. You will need to pass remove the RollnLock first before disconnecting from your point. Then connect your biner to your new anchor point, before reconnecting the RollnLock. If you relocate frequently, this extra step may become annoying.It is great for strait up and down, as pulley. You just need to make sure you don't side load it and use a correct carabiner.

After a lot of research, I used this for some roof inspections, as a backup for fall (slip) protection on 6:12 sloped metal roofs with scattered rain showers. (I'm a structural engineer.) I would not necessarily use it for a vertical drop with significant impact load, rather it was more for use where there could be a relatively small impact if I had slipped, fallen, and started to slide down the roof. Great device in such a small 'package.' (And, I haven't even used it for some of the other features it has.)One photo shows where I disconnected in order to move freely along the ridge line. In order to go up/down the opposite side of the roof, I of course had to disconnect and rotate device 180-degrees. But, it's very quick to remove and reattach to the rope mid-length.For ascent, it just follows along with you, no need to pull it by hand or pull the rope through, such as if you used a belay device you'd have to pull the rope through. For descent you need to hold it with your hand to rotate the clamp (cam) out, but if you let go, then it springs back to lock in place.(Note: I know that the quickdraw carabiner setup in the photo was not the ideal attachment, as opposed to a locking carabiner through the device, but it was the best I had at the time.)

I bought a Rollnlock 5 years ago and loved it. I use it to climb the mast on my sailboat. Today I got two more although not from Amazon. They have redesigned it and the latch open mechanism is much better. In fact if you look at online reviews on Youtube there is criticism for how easy it is to get it accidently locked open, which would be very bad. The new one is not going to have that issue. The new one is orange on one side and black on the other. The writing is different as well. You can see pictures on the CT website. The photo on this offering is of the old one but that does not mean that the product is old. You might want to contact the vendor before buying it.

I was skeptical at first but love this pulley, its extremely versatile. I use it as an ascender and bought 2 so I can set them up as a Z-rig (3:1) rescue system without the need for prusiks. I have also used it as a normal pulley as you can lock it into normal pulley mode. It seems really well made and is pretty light so you can carry it with you. I also use this as a lanyard adjust instead of a prusik knot.
