Product Technologies:

• Ball Bearing Hinge: Ball bearing hinges are designed to handle the extra stress brought on by high traffic doorways. The greased bearings reduce the rotational friction extending the life of a hinge in heavy use situations. These hinges tend to be more durable than standard, or plain bearing hinges.
• 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.
