Model: HS22.50S/R

Simple slider. This slider takes an intermediate position between two sliders with joint. It is sewed to the sail with a webbing. It usually has small dimensions as it is the slider with the lowest load in the system. Slider with joint. Its function is to be connected to a batten receptacle with a threaded pin. It is usually bigger than the simple slider because battens stress sliders more than webbings. Antal designs  mounted inside the batten pocket. Headboard slider. The slider which takes up the highest loads is realized double, triple or quadruple. With higher loads the headboard slider will need a higher number of sliders, or sliders with greater dimensions. Large mainsails or sails with wide roach require stronger headboard sliders. Headboard sliders are provided with a pivoting bracket for the coupling of the headboard. Also, Antal makes  available for a quick connection between sail and slider. Double slider. Where reefing points are and in correspondence of the clew angle, one may want to use a double slider with a double webbing connection to the sail. This because the outhaul and reef lines load up the tack angle at the mast.
