Red Heads, Red Devil, Anti Short Bushings

thanks joe.
Do you know when when they were required to be installed?

I believe that the early “BX” was double armored and used a brass insert as the bushing to protect the wires from abrasion. If you search these books](http://books.google.com/books?q=bx+cable&um=1&as_brr=1)you may find what you need.

They were always required, but the material did change over time. Type AC cable (formerly called BX cable) always required the use of anti-short bushings. Type MC cable (very similar in appearance) does not require the use of anti-short bushings. Older type AC cable fittings don’t have the witness ports to inspect for the presence of anti-short bushings as easily as more modern fittings.

In spite of that a box of MC usually comes with a bag of read heads and I will use them

Hey I like read heads, I married one … and I like those anti-short bushings too
