Hi Joe,
I had a customer show me this plate and asked me what it was. I could only assume it was used for a porcelain type lampholder mounted on the cover but I wasn't sure.

Thank You,
Mark V. Randazzo

I could only imagine it used for a surface-mounted cleat-type lampholders, but they are intended for open, exposed wiring. Bet there's no UL on it, nor conductor-limitation markings.

Bet it gave some punch-and-die maker a red woody too.

Haven't seen a cover like that, but the hole pattern appears to match what I would call " a crows foot fixture stud " which bolted to the bottom of 8b' and 1900 boxes then could screw fixture stud extenders to support lighting fixtures.

Many years ago I hung a bunch of pendant fixtures that used these. They had a strain relief that attached to the plate (like a crows foot) and a canopy that slid up and snapped on the strain relief and hid the whole thing. Haven't seen these for a while.

Besides lampholders, the more common use of this cover plate, in my experience, was for mounting the old round, porcelain-backed twist switches. The narrow slots accepted the mounting screws (bolt and nut) and the wider "clover leaf" allowed the conductors to enter the holes in the back of the switches.
