Our Rudder Pintles are available with either 8mm or 10mm Pintle Pins and with 2 or 3 hole fixings on each side of the straps. All of our rudder fittings have 5mm fixing holes. Typically a 2 hole fitting is used at the top of the rudder/stock and a 3 hole at the bottom however there is no harm in having a 3 hole fitting at the top also for added strength. Our transom fittings only work with other Sea Sure fittings as the diameter of the pins are different to that of other manufacturers.
