Abstract
An electrical device such as a panel meter with a body including an abutment, is inserted through an opening in a panel with the abutment on one side of the panel, and is secured to the panel with a nut plate on the other side of the panel. The body of the meter has plural teeth, discontinuous around the periphery of the body and the teeth extend from opposite sides of the body. The nut plate has an opening with flexible sides to enable snapping the nut plate over the body and teeth to a position abutting the panel to clamp the meter to the panel. Portions of the opening in the nut plate are enlarged so that moving the nut plate to a position in which the body teeth are adjacent the enlarged portions of the opening releases the nut to permit immediate and rapid removal of the meter from the panel. There are several teeth at each side of the body to enable mounting and securing the meter in panels of substantially different thicknesses. Spacers on a front face of the nut plate permit the resilient sides of the nut plate to be snapped over the meter body teeth close to the panel while spacing the nut plate from the panel so the nut plate exerts a bias or pull on the meter which maintains the meter firmly in position on the panel, irrespective of the thickness of the panel.
