Product Technologies:

• Plain Bearing Hinge: Plain bearing hinges feature knuckles that are machined to a smooth surface, allowing them to move against one another without bearings. Plain bearing hinges are not recommended for heavy use on high traffic entrance ways, but meet the need of a standard residential door.

• Material Type: Steel is cheap, strong, and durable, making it a favorite for hinges of all types, despite it being slightly 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.
