Included in the package are 4 different colored Eight Away's ranging in material hardness. Orange being the hardest to black and pink being softest. Decreasing the circumference of the knot on the open end of the rope will also decrease the tension between the rope and the Eight Away. The best way to do this is to slowly burn/melt the knot until desired circumference is reached. This method allows you a more flexible approach to achieving the desired tension. The last method is to clip the round end of the Eight Away in 1/8" increments until desired tension is achieved.
