Important Application Notes

To ensure the safety and longevity of your hardware, please observe the following industry standards regarding plain bearing hinges:

• Fire Door Compliance: For UL Fire Rated Doors, building codes require the use of ball bearing hinges (such as the Hager BB1279) rather than plain bearing models.
• Door Closers: If your door is equipped with a surface-mounted or overhead closer, ball bearing hinges are highly recommended to handle the additional lateral tension and weight.
• Finish Options: This steel hinge is available in a variety of high-quality plated finishes to match your existing lever sets and deadbolts.
