There's an entire world of objects that were invented and manufactured exclusively for "the office", but it opens up a gigantic can of worms that few have dared to delve into.
A few that may have been mentioned here:
Art Metal Works, Newark, NJ (aka "Ronson")
Art Steel Co., New York, NY
Geo. J. Meyer Co., Milwaukee, WI
Yawman & Erbe, Rochester, NY
Eclipse Office Furniture Co., Ltd., Ottawa, Ontario, Canada
There is a website dedicated solely to this genre:

Personally I find it all fascinating. Others - not so much.
These "gray areas" delve into industries and trades that are not really "garage" related, so they tend to be ignored here for reasons which are more than understandable - we don't spend a lot of time discussing manufacturers of horse collars or pointe shoes here either.
