How to install fire door closer

[freddiemercurystwin]

You can buy DDA compliant closers (that is requires little force to open but are still effective) for about £80. It can be worth fitting door finger guards and such things are often fitted in schools etc. DDA concealed closers start at about £160 I think.

I find your assertion unpersuasive

There's the point I disagree on; the undamped force they apply relates to the preload on the spring. You preload it a little and it works well to close the door gently when it's open to a large angle, but it won't close the door from a small angle. You preload it more so it closes the door effectively from a small angle and it slams it when opened to a large angle

I'm afraid you're never going to convince me that a 5 quid solid Chinesium door closer is in any way comparable to to an overhead, variably damped closer, particularly when considering risk of injury to vulnerable users

Damped concealed closers exist, but they are in a completely different league to the one being discussed

The particular Chinese closer in the link is something I would never fit, I agree.
But as you said, there are different standards.

Do you have any links?

The jamb closers I'm thinking of are manufactured by Barymatic (they're a residential only application, mind) but I'm sure others exist.

If you google "commercial concealed door closer" you should find some ones that are similar to the face mounted angled-arm ones, but that you bury in the top of the door, for example
