b'Q5 Quintessential, Yachting DevelopmentsChris LewisMKIV HYDRAULIC JIB REEFING & FURLINGPowerful performance packed into a compact, slim profile makes our hydraulic headsail furlers the ultimate in push-button sail control. Perfect for cruisers and performance cruisers, these free-rolling systems fit wire sizes from 11 - 25 mm (7/16" - 1"); rod from -22 to -115 or equivalentfiber stays. Parts and service are available around the world.Low-friction efficiency for easy furling and reefing Multiple rows of Torlon ball bearings in high-load areas minimize friction.Stacked bearing races evenly distribute radial and thrust loads; halyard swivel turns freely under load.Standard transmission reduces mechanical friction and pressure loss Engages/disengages the motors powered and manual gear drive for efficient operation. Worm gear drive prevents backwinding; unloads hydraulic motor when reefed.High-strength, lightweight Hardcoat-anodized, UV-stabilized aluminum torque tube, motor, and gear housing. Aerodynamic, clear-anodized aluminum Air foils Foil joints handle extreme reefing loads; carbon fiber foils available on request. Triple-interlock foil joints withstand years of torque loading: foil connectors geometric shape interlocks with foil; secures with syringe-injected adhesive; screws provide final lock.Carbon foilDO NOT use Harken equipment for human suspension unless product is specifically certified and labeled for such use.184'
