Whether for private homes or contemporary office buildings, door closer systems from dormakaba are intelligent, integrated access solutions that combine consistency, convenience, design and premium quality.


Need a door closer? If you need a door closer, you will need to know a few details. Not all door closers are the same. There are differences for specific needs, weights, and locations. Most important is what will the door in question be used for.


  • Is it a Fire Door Exit?

  • Is it for residential?

  • Is it for disabled access?

  • Is it for old and frail people?

  • Is it for high traffic areas?

  • Is it subjected to the elements?

  • How heavy is the door?

  • How wide is the door?

These questions and more are important and will help select the best door closer for your use.


We could sell you a door closer (with our eyes closed) or we could help you select the right door closer for the purpose it is intended for. We will ask you the questions. You can raise your own questions.


At Architectural Design Hardware we will help you find the right direction. Our showroom is open.


The wide-ranging product portfolio satisfies a broad spectrum of functional requirements and thus offers solutions for almost any individual door situation.


EN Ratings - choosing your door closer


Door Closers are rated by opening/closing force "Size". The Size ratings are from EN1 to EN6, with Size EN1 the weakest strength and Size EN6 the strongest. EN1 is also suitable for disabled door applications.


  • Size #1 = 0.45 of a kilogram closing force, minimum

  • Size #2 = 0.9 of a kilogram closing force, minimum ~standard door width ≤ 850 mm

  • Size #3 = 1.36 of a kilogram closing force, minimum ~standard door width ≤ 950 mm

  • Size #4 = 1.81 of a kilogram closing force, minimum ~standard door width ≤ 1100 mm

  • Size #5 = 2.26 of a kilogram closing force, minimum ~standard door width ≤ 1600 mm

  • Size #6 = 2.72 of a kilogram closing force, minimum ~standard door width ≤ 1600 mm


Many popular door closers have an adjustable open/close or latch speed setting. Example: If a door closer is listed with a open/close or latch speed of 3-6 then it is adjustable through the Power range of EN3 (1.36 kg of force) to EN6 (2.72 kg of force).
