Mounting bracket for lighting fixture auto lifter

Abstract

This is a mounting bracket for connecting lighting fixtures to autolifters. There are various models of autolifters, but most have mounting holes in four equally spaced locations on a 73mm diameter circle, or four equally spaced locations on an 84mm diameter circle. This item has long, narrow holes that can accommodate both, making it compatible with the vast majority of autolifters. It also has slit-shaped holes, so it can be used with models that require two screws, and the pitch of the mounting position is not an issue. Some autolifters are attached by sliding a metal plate on the lighting fixture into a wiring box located in the lifting section, and this slit-shaped hole can be used to secure the metal plate.
