Self-aligning canopy structure for connection to a mounting plate adapter utilized for attaching an exit sign to a junction box

摘要

A structure for aligning a canopy for an exit sign with a standard wall-mounted electrical junction box. The structure is constituted of a separate plate which is adapted to be fastened to the back cover of an exit sign so as to form a mounting structure adapted for facilitating the attachment of the exit sign to a wall-mounted electrical junction box, and which incorporates slots adapted to be engaged by protuberances on the canopy for aligning the latter with the junction box in predetermined selective orientations.
