Size 3 Door Closers
Shop Size 3 Door Closers for Fire and Internal Doors
Looking to buy a Size 3 door closer that’s compliant, reliable, and suited to fire-rated or internal doors? Our expertly selected range helps ensure safety and smooth functionality in both residential and commercial settings.
What is a Size 3 Door Closer?
A Size 3 door closer refers to the power size classification under EN 1154, suitable for internal doors up to 950mm wide and weighing up to 60kg. These are ideal for light- to medium-traffic environments like offices, flats, small commercial units, and compliant fire door installations.
Whether you're fitting a timber fire door or a standard corridor door, size 3 closers offer just the right closing force for safety without slamming. They are commonly used in fire-rated timber doors, thanks to their balance of control and compliance.
Where Should Size 3 Door Closers Be Used?
These closers are recommended for residential or light-commercial doors that don’t require heavy-duty control. For larger doors or higher-traffic areas, see our ranges of Size 2–4 door closers, Size 2–5 door closers, or Size 2–6 door closers.
All models are tested to BS EN 1154 and are compatible with a wide range of architectural ironmongery available from Trade Door Handles.
We offer both surface-mounted size 3 door closers and versions with optional cover plates to suit your design preferences. Choose from trusted UK brands like Dorma, GEZE, Briton, Rutland, and more.

More About Size 3 Door Closers
Choosing the Right Door Closer for Your Property
Size 3 door closers are a practical solution for those seeking a balance between fire safety and everyday usability. Whether you’re installing on a flat entrance or internal office door, these closers deliver reliable closing force without excess resistance. For projects that demand flexibility, consider a multi-power closer such as a Size 2–4 or Size 2–6 model to accommodate heavier or wider doors.
Most fixed power Size 3 door closers are supplied with a Fig. 66 parallel arm bracket, which is typically used in applications where the closer is installed on the push side of the door. However, using a Fig. 66 bracket reduces the effective closing strength of the door closer. For this reason, it should only be used on non-fire rated doors.
If you require a Fig. 66 bracket for a fire door, it is essential to upgrade to a minimum Size 2–4 adjustable closer to ensure compliance with fire safety standards and maintain sufficient closing force.
