Beschreibung
Zusammenfassung:	A mounting plate assembly has a mounting plate for mounting a light fixture in holes of different diameters and wherein a guide rail assembly is secured to a rear face of the mounting plate on opposed sides of an aperture. Each guide rail assembly has a novel displaceable spring clamp structure having to a displaceable base coupled for sliding displacement along a guide rail assembly. Spring biasing elements are provided between the displaceable base and the guide rail assembly to urge a bottom face of the displaceable base against a flat top surface of a mounting base to which the guide rails are secured. A retention formation is provided in the bottom surface of the displaceable base for retention coupling with a selected one of space-apart engageable retainers immovably secured to the flat top surface of the mounting base and aligned with the retention formation to arrest the displaceable base at a desired location to position the spring clamp structures at a desired location with respect to the size of a hole formed in the sheet material and to which a light fixture is to be secured.
