"With over 25 years of furling experience, Schaefer has cultivated a jib furling and reefing system that is not only durable but easy to control, smooth and dependable.Our largest furler, System 4100 has the engineered-in strength to handle very heavy furling loads. Huge, 1/2 in. Torlon\uFF99 bearings are combined with a powerful, large diameter drum to provide efficient, rugged furling for the largest headsails. This tough, winch-able design is an affordable alternative to the high costs associated with hydraulic or electric systems.Schaefer's system utilizes you existing headstay and turnbuckle resulting in full turnbuckle adjustability, optimum performance at a reduced cost. The heavy duty base toggle articulates to absorb side loads that might otherwise cause turnbuckle fatigue. The Torlon bearings used will not corrode and ride in open, easily accessible races that do not require lubrication. These proven, high compression strength bearings provide low friction, and need only periodic flushing with fresh water. Powerful, large diameter drums provide you with the mechanical advantage you need for high sailing loads. Standard split drum plates allow for easy conversion to a full length headsail.Schaefer's CNC machined metal construction resists ultraviolet rays and abuse from anchor chains and poles mounted near the stemhead fitting."^^<http://www.w3.org/2001/XMLSchema#string>
