Abstract: A mounting bracket for mounting an exterior luminare on a support pole is described. The bracket is intended to be secured by compression fastening within the hollow upper end of the pole and to mount a support for individual luminares. The compression connection includes a lower compression plate, an intermediate cylindrical sleeve, and an upper compression plate which rests on the open top of the support pole. O-rings are disposed respectively between the lower plate and the sleeve and between the upper plate and the sleeve, and an axial rod is provided which extends through both plates and the sleeve so that the rod can be used to draw the plates together, and cause the O-rings to expand into a wedging relationship with the interior surface of the pole. The rod then in turn mounts an upper support for the luminare fixtures.
