Abstract
Abstract A mounting plate for attachment to a wall or the like where a hole or aperture has been cut in the wall. The mounting plate comprises a generally planar base and a plurality of resilient fingers extending from one surface of the base. The fingers include a wall engaging surface facing the base to engage the back of the wall. The base has wall engaging contact areas spaced from the base and movable against a bias towards the base whereby the spacing between the wall engaging surfaces and the wall engaging contact areas is variable by movement of the wall engaging contact areas towards the base against the bias. The mounting plate in a preferred embodiment has anti-rotation means on the wall engaging contact areas to prevent movement of the mounting plate once attached to the wall.
