Perfect for use with our survival tarps or military ponchos to make a shelter, the Nite Ize Figure 9 Tent Line Kit. Includes four black composition rope tighteners and four 8ft. x 2.44 mm reflective ropes. These make rigging a shelter lighting quick- just loop your rope through its strategically designed prongs, pull it tight, and it stays that way. No knots needed, and it takes down just as quick.
