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

The CamJam XLs are an excellent product. I use them to secure a “Movies in the Park” screen using 1/4” double braid boat anchor rope. I usually set up 4 anchors on my screen. Once in place, I can easily adjust the tension. I’ve been using them for two years now and they have never failed. Quick to set-up and quick to release. I highly recommend this product.

I don't normally write reviews, but this product worked really well for me so I thought I'd endorse it. It's rock solid and work well to grasp the rope in the cam with no slippage. I use two of them to suspend my 130 pound kayak while I work on it. I use a 1/4" rope with it.

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

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.

Excelent i should have bought 2

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.

Great for tarps, or, sunshades!These are amazing! I've swapped out just rope with hitch knots etc. etc. life changing for me. No more struggling to install my large sunshades, 20'x20'. Using these makes the task simple and super fast. They are worth every penny.

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.
