Nite Ize CamJam XT Aluminum Rope Tightener, Large - Versatile Tie Down Cam Mechanism with Carabiner Clip - Secure Hiking Gear Essential - Rope Tie Down Accessory - Large, Black

works great. good build quality at a fair price. easy to use and small profile makes it worth keeping around for securing items

I always forget how to ties knots since I don't use them frequently. These camjams are the answer to my prayers. So simple to use, just clip like any carabiner. The rope locking cam works great and seems secure. I have pulled hard on it to tension the rope down and it has not slipped yet. The large size can use anything from paracord upto 3/8" sized double braid rope. Seems very strong and sturdy. Get the XT (aluminum) ones, the regular plastic camjams seem like a fragile plastic toy. The one thing I don't like about these are the cost....damn they are expensive.

Fantastic item, I have used them to secure large heavy items to a hand-truck, camping, hammocks, tarps, tents, securing kayaks to vehicles - I have never had a problem or any issues. As far as uses, they're only as limited as the imagination. It is a gadget, and it has multiple, multiple uses.

Not as great as I thought it would be. It does work but it doesn’t get as tight as I would like. So it will not take the place of a ratchet strap. I keep it with some 1/4” rope and assorted ratchet straps in a bag in my truck. I got it for my new truck in case I need to tie something in the bed. If I’m going to be hauling or carrying anything I would use the old truck with all the gear for that. We were out one day and the wife pickup some things from a resale shop so that was a good time to try it. I ended up tying 2 loops in the rope and putting a heavy duty zip tie in them to tighten it up. I’ll keep it but doubt I actually use it much. I could see using it while camping to secure a tarp that’s used over head.

I've only had a chance to do some basic tests with this but the cam on here is strong. It really does hold the rope in there VERY tight and is super simple to use. Looking forward to when I actually need to use this thing.

Bought this to use for tie downs for my dogs at camp , they work perfectly & they don't come loose once you cinch them & they're easy to unclip & use ! Will buy again , they are awesome 😎

I have a bunch of the lighter version of the product, made of some plastic composite, that I have permanently attached to a bunch of guy lines for tents and rain/shade flys. This one is going to live on a 40-foot rapid-deployment tarp ridgeline that’s made with 750-pound test paracord, but the tension on that line is never going to get anywhere near the rated failure load for this device, let alone for the line itself. One thing I like about the whole system is that if you have them pre-installed on a length of line with a fixed loop at one end and a stopper knot at the other end, you can tension the line in pitch darkness, just by feeling which side the stopper knot is on. Hook the CamJam into a grommet, a D-ring, a Prusik loop, a webbing loop, or whatever, feel for the knot, and just pull your line until it’s as tight as you want it. Your line is oriented just right for where it needs to be to get fixed by the cam. Takes less time to do than it just did for me to write this.

I am imaging that the people mentioning slippage in their reviews are using something like polypropylene which is a self lubricating plastic. I know from trial and error that poly hollow braid is about the worst when it comes to these cams. The common spiral twist nylon doesn't do well either because the twist makes you lose some contact with the cam's teeth. I've found that these work very well with 750 and 850 paracord but just about any natural fiber or maybe even tight weave nylon rope should do the trick. Using the 750/850 combination is indispensable for me while hanging a large tarp over my tents by myself. It allows for easy adjustments and I've never had a bit of slipping. They *are* a bit on the pricey side, but I don't mind paying for quality. Highly recommended bit of gear!
