Product Technologies:

• Material - Solid Brass: Solid brass is prized for its resilience, durability, and beauty. It can always be polished back to its original sheen and is highly resistant to rusting. Solid brass is often available in finishes that other hinge materials are not.

• 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.

• Mortise Hinge: 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.
