Abstract: An attachment system for use in mounting a monitor to a fixture. The system includes a monitor housing that houses a monitor and a fixture housing that attaches to a fixture, where the monitor housing mounts to a recess within the fixture housing. The fixture housing has a hinged tongue-groove joint that allows the monitor housing to engage and disengage with the hinged joint at an installation angle, but does not allow the monitor housing to disengage from the fixture housing at an installed angle. In the engaged position, the monitor housing can rotate relative to the fixture housing via the hinged tongue-groove joint, and can be locked in position to prevent rotation using a locking mechanism. The hinged tongue-groove joint can be tapered to improve self-alignment during installation, and can be configured to elastically compress in the installed angle to minimize movement when installed.
