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.
  • Mortise Hinge: Mortise door hinges mount flush with the surface of the 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 the current hinges before making a purchase.
  • Material - Steel: Steel is strong, durable and inexpensive; making it a favorite for hinges of all types. Steel is slightly more prone to rusting than solid brass or stainless steel.
