Adjustable Back Check
Some door closers have a back check feature which prevents the door from being opened too quickly. Usually the door closer will have a valve located somewhere on the main body of the device which allows the amount of resistance to be adjusted.
Adjustable Latching Action
During the last 15° of closure a door closer has to cope with the increased resistance provided by the door latch. Door closers with an adjustable latching action will have a means of increasing/decreasing the closing force for the last 15° of closure to ensure that the door latches firmly and securely.
