Find some that come with steel brackets
on January 8, 2016
I bought a pair of low-voltage portholes exactly like this from Amazon a few years ago for the intended purpose, and they were great. Recently I ordered a second pair of these units, believing them to be identical to my original pair. oops. I didn't notice that they DO NOT come with the steel plates that insert to the drywall. Consequently I had to go out in search of a pair of steel plates that provided the four threaded holes to affix the white plastic pie to the drywall. All I could find were flat steel plates...which were nearly impossible to install, because they did not affix to the drywall; I had to hold each plate with my fingers poking through the plastic porthole whilst trying to BLINDLY line up the screw holes. It was a nightmare. Once they were in they were fine, but holy smokes I would NOT do it that way again.
