Abstract: A telephone housing is mounted on a metal plate that is secured in a fixed location on a room wall. The mounting plate has two vertical flanges extending along its side edges; hooks project forwardly from the flanges, for interengagement with vertical slots formed in the housing rear wall. At its lower edge, the mounting plate has two forwardly extending tabs that form two additional hooks. Additional slots in the telephone housing rear wall receive the two additional hooks to provide additional support for the housing. The preferred mounting plate is formed out of sheet aluminum by a stamping and bending process.
