Ok, let me explain.
I live in this appt complex with a real long hallway.
There's 3 exit doors plus all the appt entrances.
Exit doors have closers on them and I have adjusted these
repeatedly so the doors close slowly.
The problem that remains is the latch makes a loud
snapping noise when the door has completed closing.
I tried to muffle it with some cotton but that also
Since there is traffic through here day and night,
the snapping is going virtually around the clock.
Is there any way to adjust or muffle such things
so the residents like me can sleep?
