Door Stop Installation
A hard door stop must be used to prevent the door from traveling past 90 degrees when opening. A hinge mounted
standard duty door stop is included in the CONCIERGE 23DR package. To install this door stop, first remove the hinge
pin from the top door hinge, reinsert the pin with the door stop in place, then adjust the threaded post so the door
stops at 90 degrees when open (see DIAGRAM below).
A heavy duty door stop (not included) is recommended for heavier doors.
