Was it because of the common (albeit dangerous and 'illegal') practice of wiring one of these with heavy duty cord to make a "handy" convenience outlet extension cord?
I get the impression the only proper use for the handybox is surface mount wiring with conduit or armored cable.
I also can't see how you would use this inside a hollow wall without a support bracket.
And while some people may think you can use them inside solid concrete walls, isn't there a specific "masonry" box listed for this purpose?
Is this true?
A "self help" book sold at a major DIY shed has a picture of what looks like a handybox (stamped onepiece thing with rounded corners) inside a wall in their chapter on temporary repairs of crumbling insulation inside the box with a heatshrink sleeve
Of course this could be a staged thing on a piece of "fake" wall but you think that these books would go through the effort of showing "the proper devices" in use at all times.
