Selden Heel Adapter that is suitable for section, Gamma.
Selden reengineered their entire range of mast and boom fittings in 2003. These fittings come standard on all new spars, but can be retrofitted to older masts and booms with adapters.
Injection molded from an advanced composite, the new mast heel and the adaptors are significantly lighter in weight than aluminum ones, have high shear strength and are very durable. Unlike the more traditional alloy mast heel, this new range does not react with carbon.
