Abstract
Abstract A quick install device for mounting a luminaire on a flat surface such as a ceiling, a wall or the like, is disclosed. The device comprises in the preferred embodiment a mounting plate which is fixedly attached to an existing outlet box in the ceiling or wall and a luminaire plate which is fixedly attached to the luminaire. The luminaire plate and the mounting plate contain means for quickly attaching the two plates together with the attached plates serving as a splice chamber for containing the electrical splices used in electrically connecting the luminaire to an electrical circuit. The mounting plate structure and the luminaire plate structure may be reversed in actual use as desired by the purchaser of the device for different types of luminaire mountings.
