Product Technologies:

• Spring Hinge: These single action hinges are fitted with springs in the barrel to bring an open door back to a closed position automatically. Great where door space is at a premium and door closers are impractical. With double action hinges, the door is able to move in either direction.

• Material - Steel: Steel is cheap strong and durable making it a favorite for hinges of all types. Though it is more prone to rusting than solid brass or stainless steel.

• Mortise Hinges: Mortise door hinges mount flush with the surface of your door, providing maximum strength with the least interference with door functionality. It is recommended that three hinges be used on doors up to and including 7-1/2 feet, with one additional hinge for each additional 2-1/2 feet. Be sure to check your current hinges before making a purchase.
