My flat door, which is a fire door has a Briton 121 CE door closer.
I can quite crudely adjust the closing speed but the latching action
adjustment screw seems to have little or no effect on the last 15
degrees or so of closing. The choices there seem to be rip your arm
off if trying to hold it back, or chop your fingers off if you don't
get out quick enough. Both options would include an almighty bang.

Is finer adjustment of this particular closer likely to be possible
somehow?

Or maybe a more expensive fire door certified closer with more subtle
adjustments would be the answer?
