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 .

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 item really pleased used to keep stuff on car roof rack - easy to use and never came loose very good purchase!

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

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.

I have some of these in all my tent bags and my popup gazebo bag. They're easy to connect and quickly add tension to a line.

Ottimo moschettone, super comodo e robusto
