NCJ-01-4R3 CamJam Tie Down Rope Carabiner Clip, Cord Tightener 4-Pack, 4 Count

All "Nite Ize" products are awesome. These are snap hooks with a "Jam Cleat" mechanism incorporated. These are VERY well built. "Nite Ize" is totally pro, and totally reliable.

For cord sizes: 1/16 inch to 3/16 inch or 2mm - 5mm (2mm - 5mm is molded onto the surface of the cam) Very rapid deployment. Just pull in-line - away from the hook - to tighten. Very rapid removal. Just pull to the side to release. Reliable and secure, will hold very well. These are designed for "light loads" only. The company doesn't state a capacity. Search Amazon for other "Nite Ize" products like the "S-Biner" (I have about 80 of these in sizes: 1, 2, 3, 4, 5, ( all Steel), and in plastic I have sizes 0, 8, & 10. These are all similar to "carabineers," except these have 2 gates and a central diagonal bar which together define two separated capture regions. These bind, but still separate cords, ropes, rings, etc. into 2 sections in one device. There are numerous versions: locking, bottle opener, LED light, key ring, plus combinations of these features. "Nite Ize" has many more products that may help you, and that make solid, useable, high quality, thoughtful gifts.

We have bought these several times they work great on tarps and or other items such as tents, etc. would recommend and purchase again. They’re also very durable. We have not had one break yet.

These don’t have a specified load capacity in the literature, so I ran a basic test using a one-gallon jug of water tied by its handle with a length of well-used 550 paracord. I bought a 4-pack and tested each one by lifting the jug and bobbing it up and down to simulate light wind gusts on a tarp. All the cord tighteners held the load reliably without noticeable slippage. I didn’t test beyond around 25# surges or an 8-9# static load, but they at least held up to that. In contrast, I had purchased a 6-pack of knockoff devices that looked identical in the Amazon ad. Only one of the six knockoff tighteners managed to lift the jug under similar static 8-9# load conditions. Using two of these might work for hanging a kayak or even a bicycle in a garage, but for a few dollars more, you might want to go for the next grade up with aluminum or zinc alloy construction for heavier loads. To be clear, these are very functional for light-duty use and very convenient, though CamJam offers better options for more demanding tasks. Update: I found that if I wrapped the paracord through the routing hole and around the fixed end of the gate spring then back through the routing hole before pulling it into the clamping mechanism the device can hold roughly 30# of tension reliably. The weak point in this configuration is the 180-degree curved hook the gate spring closes on. I can easily see that curve distorting at that point. I definitely trust these little cord tighteners but personally will not load them past 10 to 15#. The 280# and 1500# break strength (100 and 500# working load) aluminum models are not that much larger.

Carry these in my kit for all travels as they come in handy for many reasons - I have strung up clothing lines for wet clothing, hung washing bags in the bathroom for easier access while keeping them off of the counter ... just about anything you need. The quality is incredible - SOLID. Easy to use. Easy to attach. The 550-cord is a bit short but easy enough to add more or change to a longer length.

Wow! I have needed these my entire adult life. I have been boating, motorcycling, and camping for thirty years or more, and that includes lots of rope, cords, and knots. Every year i review my knot tieing book before boat season, but in 20 years, my memory continues to forget knots. I can do square knots and some clove hitch variations, but thats all that sticks. These cam lock carabiners are amazing. I saw one on a friend's boat and had to buy some. I use them to keep boat covers tight, to keep the cover hem line taught, and to adjust fender rope heights quickly. They are great for blue tarp hanging, strapping stuff to cargo carriers. Get some paracord and the possibilities are endless. I bought 4 plastic can jams for light work, and 4 aluminum for heavier loads. The aluminum ones come in 2 sizes. The large are for 1/4 Inch rope and up ( boat stuff). The regular small ones are for paracord. Expensive, but worth the functionality. Get one to try!

Pretty slick! Purchased the size comparable with 550 paracord. Keep a set in my truck and a set in my car along with cord to keep things secure. Used those in my car just this weekend to keep a cooler secure for a family picnic. Worked great!

Product is ok its the packaging that is treacherous. I wonder how many people cut themselves trying to cut the zip ties? Probably one in 5. Some will need stiches. Use channel locks to break the ties. Grab them and twist them. Some of this packaging these days is ABSOLUTELY TREACHEROUS!. [trap] Pisses me off.

Great for travel. I've used these several times for making a clothesline on my hotel balcony. I bought a second set just because I loved it so much. We once rigged up an impromptu badminton "line" with these. You could easily pair these with a tarp for emergency shelter (in which case you may want two sets). Sets up easily, secure, it simply works well. Recommended.

Great little bit of kit! Super easy to use! No fussing about with having to tie off ropes/cords.

pratique et facile à installer ; bloque bien la corde .

Amazing how many uses this has

Amo esta marca, todos sus productos son perfectos. Excelente artículo, fácil de usar, buena calidad, funciona increíble. Lo usaré para poner una carpa con postes en el campismo. El plástico se siente bastante sólido y resistente, el resorte del mosquetón regresa fuerte y el tensor de cuerda no libera nada en contrasentido de la tensión. Después compraré más. ACTUALIZACIÓN - No lo usen en la playa, puse un toldo y la arena se metió al espacio donde traba el gancho el cordón... Desde entonces se atasca y ya no funciona. Pero no es algo propio del producto, sino un error como usuario. Cómo tal el producto es muy bueno.
