Baldwin 1/4" Radius Corner 4" x 4" Solid Brass Plain Bearing Mortise Hinge - Single Hinge

Baldwin's top of the line hinges set industry standards for excellence. These elegant hinges are available in several finishes to discretely accent your home while bringing the dependable performance you need.

Manufactured from solid brass extrusions for both exceptional strength and precision tolerances, Baldwin hinges are individually machined from a solid brass bar resulting in a high quality hinge with increased wear performance. Each hinge is beveled on the inside leaf to obtain a perfect fit when closed.

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.
