Abstract: This invention is a prefabricated very strong in wall support for universal fixtures mounted on a wall. Fixture support connectors or arms extend from the support and hold up the fixture. The in wall support is rigidly bolted to the floor so the support bears all the weight of the fixture and transmits the weight directly to the floor. The support is manufactured to accommodate standard fixtures. The height of the mounted fixture can be varied by moving the brackets which hold the fixture support connectors up and down. Brackets can be mounted on both the front and back of the support, thereby allowing the mounting of a fixture on both sides of a wall using a single support.
