Double doors are commonly used in various places, such as commercial buildings, schools, hospitals, and large public spaces. These door closers are often used to accommodate high traffic and improve accessibility. Heavy duty door hinges are ideal for double doors, as they are easy to install and fit on a wide variety of door sizes.

Self Closing: the Necessity and Challenges in Unequal Double Door Systems

Self-closing function is often necessary on double doors.  Because double doors are often installed in commercial or public buildings, the self-closing function helps ensure that the doors close automatically after being opened.  This can be important for maintaining fire safety, controlling air circulation, and meeting ADA accessibility requirements. Very often, the two doors are of unequal size, where one door may be twice as wide as the other.

For example, a 5’ opening may have one 3’ door and one 2’ in order to meet the 32” clearance requirement.  This poses a self-closing device installation challenge due to limited space on the narrow door, which can lead to hardware function incompatibility.  In addition, mixing models causes poor symmetry and an unattractive aesthetic.

Commercial Double Door Closer Solution 

Waterson heavy-duty closer hinges stand out as the ideal choice for managing double doors in commercial settings. Their ease of installation accommodates both wide and narrow door configurations, eliminating the need for the extra space that traditional, bulky closers demand. Beyond functionality, the double door closer hinges elevate the aesthetic appeal of doorways with their sleek and stylish design. Meeting critical industry certifications, these hinges are UL Grade 1 approved and ADA compliant, making them a go-to option for ensuring safety and accessibility.

Code Compliance and Safety 

The specific codes and regulations for double doors can vary depending on location and building purpose. In the States, building codes are usually adopted at the state or local level, and they are based on international or national codes like the International Building Code (IBC).  If you’re planning to install or modify double doors, it’s important to consult with local building authorities or professionals who are knowledgeable about the relevant building codes to ensure compliance and safety.
