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 - Solid Brass: Solid brass is made from copper and zinc and is prized for its resilience; durability; and beauty. Solid brass 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.

Mounting: The standard corners for mortised door hinges are 1/4' radius; 5/8' radius and square corner. It is recommended that three hinges be used on doors up to and including 7.5 feet with one additional hinge for each additional 2.5 feet. Make sure you check your current hinges before making a purchase.
