400lb 100% Dupont Kevlar Braided Line, 1.7mm Dia, Cut and Abrasion Resistant, Low Stretch, Heat Tolerant to 900 f(heavy duty speargun band constrictor line, model rocket paracord, survival/tactical);

Spearit's 1.7mm Kevlar line is a great heavy duty constrictor for thicker band rubber (greater than 5/8") and for those spearos that really want to strangle their tubing. Kevlar's ultra high strength, low stretch and superior knot retention mean that once tightened, your constrictor knot will stay tight. Avoid the problems of knot creep or stretch inherent in other synthetic fiber cords. Near zero stretch allows the use of smaller, rubber-saving wishbone terminals. Forget melting the end of your constrictor to keep the knot from slipping out. For a clean finish you can tie an extra constrictor with the knot tails and trim the excess cord flush with the knot. Its high strength to weight ratio and toughness make it a great tactical/survival accessory for outdoor activity. With a nearly weightless small coil of this cord in your pocket you've got extra fishing line, tent stays, snare line, sewing thread or 1000 other ways to save the day. High heat tolerance (to 900+ f), make it an excellent: model rockets paracord and fire poi accessory. This cord is braided from 100% Kevlar fiber made in the USA by Dupont and then is assembled and tested by a US defense contractor. Unlike some of our competitors, there is no fine print about fiber blending, braid components that are not Kevlar or generic substitution.
