Ensure your premises are safe, accessible, and fully compliant with our professional range of magnetic door holders. Designed to hold heavy fire doors open during everyday use, these electromagnetic retainers are wired to your building's fire alarm system. In the event of an emergency, the power is cut, releasing the doors to prevent the spread of smoke and fire. Browse our selection of wall-mounted and floor-mounted door holders below to find the perfect fit for your security and safety needs.
Reliable Electromagnetic Door Holders for Every Environment Whether you are managing a school, hospital, office building, or care home, maintaining a safe and accessible environment is a top priority. Standard door wedges are a major fire hazard and illegal when used on fire doors. Our electromagnetic door holders provide a legal, safe, and highly effective alternative.
By integrating seamlessly with your existing fire alarm or door entry systems, our door retainers allow high-traffic corridors to remain open, improving ventilation and accessibility for wheelchair users, while ensuring doors close automatically when the alarm sounds.
Types of Magnet Door Holders We Supply
We stock a variety of door retainers to suit different installation requirements and door weights:
-
Wall-Mounted Magnetic Holders: The most popular choice, easily installed onto the wall behind the door. Ideal for standard corridors and office spaces.
-
Floor-Mounted Magnetic Holders: Perfect for situations where wall mounting isn't possible (e.g., glass partitions or doors that open into large, open spaces).
-
Heavy-Duty Retainers: Designed with higher holding forces (measured in Newtons/N) to securely hold heavy, oversized, or high-tension fire doors.
Fully Compliant Fire Safety (BS EN 1155)
When it comes to fire safety, cutting corners is not an option. The magnetic door stops we supply at Door Entry Online are rigorously tested and manufactured to meet strict UK and European safety standards, including BS EN 1155. This guarantees that the electromagnet will reliably release the door the moment your fire alarm system is triggered or in the event of a power failure, ensuring your fire compartments remain uncompromised.

Frequently Asked Questions (FAQs)
How does a magnetic fire door holder work? The holder consists of an electromagnet (usually fitted to a wall or floor) and an armature plate (fitted to the door). When powered, the magnet holds the plate, keeping the door open. It is wired directly to the building's fire alarm system; if the alarm goes off, the power to the magnet drops out, and the door's mechanical closer shuts it.
Can I use a magnetic holder on any fire door? Yes, provided the door is equipped with a functional overhead door closer and the magnetic holder is properly wired into the fire detection system.
What holding force do I need? Standard internal doors usually require a holding force of around 200N (Newtons). For heavier doors, high-traffic areas, or areas prone to strong drafts, a 400N or 500N holder may be required.
