Abstract: An access door system for a narrow profile enclosure for housing an automatic teller machine (ATM) which allows servicing of the teller machine from within the enclosure for enhanced security for the contents of the ATM and service technician safety. The enclosure includes a door that is hinged and pivots along one vertical end surface allowing the opposite vertical edge surface to rotate away from the enclosure side surface through 30 degrees of rotation. The vertical edge surface includes a perpendicular rectilinear end wall of the same height fixedly attached at a location slightly spaced from the vertical edge surface which extends inwardly from and perpendicular thereto. The rectangular end wall is either a solid panel or has a pivotal door for enclosure entry therethrough.
