Capstan line and fixed point connection can be single or double stranded capstan line. The fromwinch electric winches for trucks single wire means that the winch wire is pulled to a fixed point and hooked directly to the D-shaped lug, which is a single wire from the car to the tree. Two-wire fromwinch electric winch for tower can be doubled. A double pulley is required, a pulley with a metal hook, or a pulley that is attached to the D-lug with a different connector. Hook the pulley onto the bolts of the D-type eyebolts on the tree belt, pull the capstan line to the pulley, and open the pulley opening to wind the capstan line around the pulley. Pull the capstan line back into the car and hang on a front trailer hook attached to the frame.
