How do I know if I need a Standard Weight or Heavy Weight hinge?
Heavy Weight hinges are generally used on solid wood or metal doors, where Standard Weight hinges are used on light-duty or hollow doors.

Cal-Royal Square Corner 4.5" x 4.5" Stainless Steel Plain Bearing Mortise Hinge - Three Hinges
Decorate your homes doors with these handsome hinges from Cal-royal. Featuring stainless steel construction and a sensible plain bearing design this hinge serves to improve your doors at the fundamental level.
Features:
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 - Stainless Steel: Stainless steel reacts with oxygen in the air to form a very thin film of chromium oxide on the surface of the steel. This helps prevent the steel inside from rusting, and is great for homes in climates prone to rusting.
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.
