Designed for large boats and for mainsails with a large roach, they offer the high strength of HS Fibre Guides (for tension load) and the low friction of the Torlon ball bearing (for compression). Maximum load because the HS fibre guides give excellent resistance to the main pull loads despite the compact size of the carriages.
Each batten end fitting is attached to a slider with a triaxial joint to ensure that the batten can freely orient itself under all points of sail. At least one simple slider should be attached to the sail with nylon webbing between two battens. A headboard is attached to the sail with webbing and is secured to the slider (double or triple) with a clevis pin which allows the headboard to pivot and to be removed.
Self-captive bearings: it’s impossible for the bearings in the slider to come out, so it’s possible to take off the sliders from the track.
