This is the perfect device for keeping your antenna support lines tight and easily adjustable. Knots are not required, just a few simple twists and your support rope is locked into place. I wish these had been available years ago. They would have made my antenna installations much easier. These tensioners are made of aluminum and will work with any rope size from 1/8" to 3/8". Complete instructions are engraved on the Rope Tensioner™. This is a high quality product that should last for years.
