Mag Hold Open

A Magnetic Hold Open, refers to a device typically used in conjunction with fire doors in commercial or public buildings. This device employs a magnet to keep the door open under normal conditions, allowing for easy passage and air circulation. In the event of a fire or when a fire alarm is triggered, the magnetic hold is released automatically, allowing the door to close. This closing action, often linked to the building’s fire alarm system, is crucial for preventing the spread of fire and smoke, thereby enhancing the safety and fire compliance of the building.
