Rim Panic Exit Devices with Mullions - What is the bar in the middle of a double door called?

Double doors are a popular choice for commercial buildings, as they provide a wider opening for people and equipment to move through. However, they can also present a unique challenge when it comes to security and safety. One of the key components of a double door is the bar in the middle that helps to keep the doors aligned and secure. This bar is called a mullion.

What is a Mullion?

A mullion is a vertical bar or divider that separates the two leaves of a double door. It is typically located in the middle of the opening and runs the full height of the door. Mullions can be made from a variety of materials, including aluminum, stainless steel, and wood, and can be designed to match the aesthetic of the surrounding door hardware.

The purpose of a mullion is to provide additional support and security to a double door. Without a mullion, the doors would be more susceptible to forced entry or being pushed out of alignment, which could lead to damage or injury. Mullions help to distribute the weight of the doors evenly and keep them properly aligned so they can function as a single unit.

Rim Panic Exit Devices with Mullions

When it comes to installing panic exit devices on double doors, a mullion can present a challenge. Panic exit devices, also known as crash bars or panic bars, are designed to allow for quick and easy exit in case of an emergency. However, in order to work properly, the exit device must be installed on a solid surface that can withstand the force of people pushing against it.

This is where rim panic exit devices come in. Rim panic exit devices are designed to be installed on the surface of the door, rather than being mortised into it. This makes them a good option for double doors with mullions, as they can be installed directly onto the mullion itself. The rim panic exit device will extend across both doors and provide a secure and easy-to-use exit in case of an emergency.

One important consideration when using rim panic exit devices with mullions is the placement of the device. It is important to ensure that the device is located at the correct height so that it can be easily accessed by people of all heights. The device should also be installed with proper clearance so that it can function properly and not be obstructed by the mullion or other door hardware.

Benefits of Rim Panic Exit Devices with Mullions

Using rim panic exit devices with mullions offers several benefits for commercial buildings:

  • Improved safety: Panic exit devices provide a quick and easy way for people to exit a building in case of an emergency. By installing them on double doors with mullions, you can provide an even safer exit option.
  • Better security: Rim panic exit devices with millions are very durable and more difficult for forced entry.
