are molded from a special blend of glass-fiber reinforced polymers to give exceptional strength and durability. All springs are made from non-corrosive, high-grade stainless steel or silicone-chrome wire for 100% rust-free hinges with infinite torsion adjustment. MULTI•FIT hinges allow for easy installation on either wall or post mounting thanks to their "multi•fit legs", and strength is not an issue either because of MULTI•FIT's ability to multiple face fix on two sides of a gate or fence post. Extra strength is also achieved on flat fixing (180°) for wall installations because the hinge offers two leafs for fixing when flattened out.
