Key Features and Functions

1. Control and Safety: Interior opening arms help to control the speed and force of door opening and closing. This prevents doors from slamming shut, reducing the risk of injury and damage.
2. Accessibility: They ensure that doors close automatically, which is essential for accessibility standards in public buildings and compliance with safety regulations.
3. Energy Efficiency: By ensuring doors close properly, these mechanisms can help in maintaining temperature control within a building, contributing to energy efficiency.

Types of Interior Opening Arms

1. Door Closers: These are devices mounted at the top of a door that automatically close the door after it has been opened. They often include an arm that connects the door closer to the door frame.
   • Surface-Mounted Door Closers: The most common type, installed on the door surface.
   • Concealed Door Closers: Installed within the door or frame, providing a cleaner appearance.
   • Floor-Spring Door Closers: Mounted in the floor, commonly used for glass doors.
2. Hydraulic or Pneumatic Door Closer Arms: These use fluid or air pressure to control the door movement, providing smooth and quiet operation.
3. Spring Hinges: Hinges with built-in springs that close the door automatically. These are simpler and less expensive than hydraulic door closers but offer less control over the closing speed.
