Digit 3:- Test door mass/size
Each number in this category identifies the closer size and its suitability for use on these doors. Adjustment strength closers are identified by showing both the minimum and maximum strength.
Digit 4:- Fire Behavior
Based on the results of the fire tests to BS476:part22. 1 is the grade given to the closers that are suitable for use on fire or smoke doors.
