Made of B-50 Dacron to use on any bow. Built using a single end loop with an adjustable timber hitch knot on the other end. In a pinch it doubles as a tillering string for bow building. Extra length has been added to the center serving to accommodate different bows. The Timber Hitch is for bows of finished length of 68"-72". Perfect for selfbows, English longbows, primitive bows, medieval bows, and other extra-long bows.
