Abstract: A weatherproof terminal or junction box structure for a luminaire adapted for connection by a mast to a building or pole. The structure enables access to the terminal or junction box area for wiring and inspection without disassembly of the mounting of the luminaire to the mast and without the necessity of disassembling the luminaire itself. The mast telescopes within a channel receiver of the luminaire housing for mounting purposes. The mast is slotted at its entry end, the slot being encompassed within an access opening which may be covered by a wire way cover.
