Product Technologies:

Ball Bearing Hinge: Ball bearing hinges are designed to handle the extra stress brought on by high traffic doorways. The greased bearings reduce the rotational friction extending the life of a hinge in heavy use situations. These hinges tend to be more durable than standard, or plain bearing hinges.
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.
