The moment you have the feeder in your hand you will see that it is a product unlike any other. The standard combination of plastic and lead was replaced by a structure made entirely out of ZINC! This gave Fortis leader extraordinary durability. We kept the tried and true, well-known shape. Fortis fits the new Mikado molds sizes L and XL. Note that the central part which guides the line is in the form of a special tube, which makes it easier to make the rig and prevents the line from fraying. We gave up using lead in the production process. This makes Fortis leaders much more environmentally friendly.
