Pulley Savers are designed to be a very simple way to back-up your bridle system and keep your wing shape from being compromised should a pulley break in flight. The pulley saver simply attaches around the pulley and bridle line to keep them attached in the event the pulley breaks during flight. Pulley savers are designed to help your wing hold shape so you can fly back to shore and keep a compromised bridle from crashing your day. Get in safely, and back on the water quickly!
