A system of mounting electrical equipment, such as loud speakers, electrical clocks, radios and the like, in an enclosure which has a grill with flanges which telescope with complementary flanges on a mounting plate. The mounting plate may be secured to walls or ceilings by flush mounting or edge mounting brackets and may be secured in either a horizontal or vertical position. If an edge mounting bracket is used, the mounting plate is a plural center ring which receives telescoping cover plates from both sides to form a clamshell enclosure. Where flush mounting is used, such as on walls or ceilings, a single telescoping ring is used, which is mounted in the wall or ceiling, and the grill work and the complementary telescoping ring is attached thereto.
