Door Retainer

Door Retainer

A door retainer holds fire doors open, preventing them from closing unintentionally. These devices are especially important in buildings to comply with fire safety regulations. They are designed to release when a fire alarm goes off, allowing the door to close automatically and contain the fire.
Some models of door retainers are activated by sound, detecting the fire alarm’s signal. These sound-activated devices make it easier to maintain fire door access without manual effort. Others use a traditional mechanism to keep the door open and only release when needed.
Available in various colors and designs, these devices can match the door’s aesthetics and the building’s overall look. Common features include easy installation, robust performance, and the ability to work with different types of fire doors.
A door retainer is essential to fire safety, especially in high-traffic areas. It helps prevent damage to fire doors while maintaining the necessary safety standards for the building and its occupants.
