F6 concealed, removable-style hinges from Southco are designed to enhance user options for durable and corrosion-resistant performance in the aerospace industry. Removable and retractable hinge-pins simplify door removal for easier access, while all-metal designs in a range of sizes provide more choices for strength and durability across a wider variety of enclosures and equipment, according to the company. Available in zinc-plated steel, 300-series stainless steel, and engineered plastic materials in sizes ranging from 0.87 to 5.91 in long, the expanded F6 hinge line is designed to provide options for a variety of environments or applications—heavy duty or lightweight, corrosive or non-corrosive. Most models are available with dual hinge points for greater stability. A non-corrosive, non-conducting engineered plastic design is also available as an alternative for lightweight applications.
