National Hardware Double-acting Spring Hinge, Nickel, 3 In.

The National Hardware N100-051 is a double-acting spring hinge designed for interior doors, cabinets, and lightweight panels that need smooth, reliable motion in both directions. Made from cold rolled steel with a satin nickel finish, this hinge resists rust and corrosion while maintaining a polished appearance in high-humidity areas like kitchens and bathrooms. Its compact 3-inch length and surface-mounting design make it ideal for tight spaces without requiring mortising, while the spring-loaded mechanism automatically returns the door to a closed position, reducing slamming and wear.

Spring hinges eliminate the need for manual door closing and are commonly used on interior door frames, cabinet doors, and office partitions where quiet, hands-free operation is valued. The double-acting design allows the door to swing freely from either side, making it versatile for high-traffic residential and light commercial applications. This hinge supports doors 3/4 to 1-3/8 inches thick with a 12 lb weight capacity.
