EXIT DEVICE ABSTRACT OF THE DISCLOSURE The present invention is an exit device providing adjustable backset. This is achieved by having the touch bar linked to a driven element adjacent the base plate of the unit and the latch mechanism linked to an activator element also adjacent the base plate. These two elements are coupled by a sliding drive plate having a plurality of sets of apertures spaced along it to receive both elements respectively in a selected set. An exterior opera- tor of specified backset is provided and connects with a cam adjacent an end of the drive plate to side the plate when the exterior operator is moved. By selecting the proper set of aper- tures for the elements the installer can see that the cam is at the proper backset and therefor aligned with the operator.
