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 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 .

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

These tighteners are a must have camping tool. It saves time setting up and tearing down (which is the most annoying part in my opinion). They are lightweight, durable, and universal for most cord you plan to use. They are a bit pricey but to have a couple in your pack, you'll thank yourself.

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.

bon produit je pense en reprendre et en trouver d'une plus grande taille

Great to hold on ends easily fir guy lines and shelter building of tarps
