NCJ-01-4R3 CamJam Cord Tightener Plastic Tie Down Mechanism, 4-Pack Without, Black

Great device's, used for canoe sailing held in strong winds and under load. Release took a bit to work out smoothly but after a week or so its great. Using 5mm cord.

I use them for my removable washing line. They are my most fantastic find in years to be able to get my line exactly as I want it. I now have a taut washing line that can also be adjusted as and when. Strong and easy to use. Love this product.

Excellent product - did what it said in the advertisement - sadly a little smaller than I had hoped for.

Very useful. I will always put a knot behind the clamp to ensure no slippage (in fairness no sign of any in practice).

Not bad for light usage but the plastic is quite weak and the rope gets caught behind the jam easily. Better pay extra for the metal version

i brought the metal versions of these before and if im honest , i would spend the extra money on them next time .... i was being cheap! these work very well but feel much cheaper and inferior . used to tie down a car cover .. useful as it keeps groveling around on a wet drive to a minimum and to be fair , used with paracord it has not come lose at all .

Bought for a family party to put up and tighten a tarp.

Lovely bit of kit, makes a very quick ridge adjustable ridge line for tarps. Cheaper and lighter than the metal ones and so far just as durable!

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

Very handy for the typical 550 paracord. Excellent for low load, like under 50lbs tension. That’s usually more than enough for lashing things down. Keep the load down and use the right size cord and these are reliable. I’ve had the cam’s pull off when pulling tension at an odd angle but they are simple to pop back into place with no ill effects. I wrapped mine in reflective tape to keep them from getting lost in the grass or the bottom of a bag. Why does everything have to be flat black? ;) I love having fewer knots to pick out when tearing down camp. I have since purchased the 280lbs and 500lbs rated aluminum ones for more demanding tasks.

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.

These are great for tie down. Work well with paracord.

これは簡単で使いやすい！ 風が強くなければ、これで事足りる。 タープ張りに使えます！
