The Super Rope Cinch is a revolutionary way to tie rope without tying or untying a knot. With a simple twist, the cinch secures ropes, holding a great amount of vertical or horizontal pressure, yet can be tied and untied in less than 1 second. To tie, insert rope and twist top clockwise. To untie, while pressing button, twist top counter-clockwise. Use for tying boats, tents, luggage, backpacks, lumber, car trunks, tools, and everything else you fasten with a rope. Strong, lightweight, and very easy-to-use. Can be used to tie 1/8" to 5/8" rope. Safer than bungee cords, which can fail and cause injuries. 12 per tray.
