Our overhead door closers control how a door closes to prevent slamming and help fire doors close fully, including adjustable-power closers, delayed-action models and electromagnetic hold-open units. Ideal for fire doors — see our fire door kits and door hinges too.

Overhead door closer buying guide

What power size do I need?

Closers are rated by power size (commonly EN 2–6) based on door width and weight. Adjustable closers cover a range of sizes, making them a flexible choice for varied doors.

What is delayed action and back check?

Delayed action slows the closing cycle to give people more time to pass through, while back check resists the door being flung open. Both are useful on busy or accessible doorways.

When would I use an electromagnetic closer?

Electromagnetic hold-open and swing-free closers keep fire doors open for everyday use and release them to close when the alarm sounds, linked to the fire system.
