Did you know that on a door with traditional butt hinges, 70% of the door weight is on the top hinge? The top hinge also bears the brunt of abuse when doors are opened beyond the stop device, resulting in kickback shock and eventual failure of the hinge and damage to the frame. This is why continuous hinges are recommended for heavy doors and for situations where doors are exposed to misuse. Continuous hinges reduce the factors leading to hinge failure by distributing weight evenly so wear and tear to the frame and door is reduced significantly.
In addition, continuous hinges:
• Increase security and reduce vandalism by preventing insertion of devices between the door and frame
• Ease installation by providing simple alignment of electrical transfers and of monitoring switches
• Reduces air infiltration by creating a complete seal from top to bottom of the door at the hinge jamb
