Nite Ize CamJam XT Aluminum Rope Tightener, Large Versatile Tie Down Cam Mechanism With Carabiner Clip + 500 LB Load Limit

Says max weight of 150lbs - I'm assuming that's being conservative because it's so solid and heavy duty.

I use it with a thick rope for hanging my washable rugs to dry. Real easy to setup and remove, and it doesn't slip. Awesome product.

The product is an excellent value and works perfectly for our RV travels

This Nite IZE Clup is exactly what I needed to secure loads quickly vs Straps .

works very well and feels durable, so far I love it

As with all Nite-I've products…. Simply superb

Surprisingly durable, used it for a rope from my front bumper to a roof carried kayak on my car.

i have several , use every day, they keep my medical scooter in place on its carrier. they are so quick and hold well. had one get dragged across town on road cause i didnt secure it, it took the road damage ok just needed to lube it and it still doing its job. i also use a figure nine on same carrier for securing other load

The CamJam XT is an overall quality product. It is well made of what appears to be high grade aluminum. The fixtures are tight and the jam function is smooth and easy to load/unload. I'm using four strand paracord and two of the smaller CamJam XT to guy an amateur radio NVIS antenna at a height of about 10 meters. The antenna and CamJam's survived Tropical Storm Isaias. I'm pleased with my purchase and highly recommend the product.

This is a very well made cord tightener. Don't by any of the plastic one, only aluminum. This work much better than I anticipated. I like being able to use different cord sizes without changing anything. Very simple and quick to adjust to the tension you need.
