Anybody correct me if I'm wrong here but yes, basically it's there for the mounting lugs to easily facilitate installation/replacement. Most tubes as we know had some sort of strapping set-up that mounted the tube to the bezel. There is the exception of some early Zenith Rectangular tubes that mounted in a "surround" then that was then bolted in, and was a PIA to unseat from the old tube during replacement.
Has anybody noticed any cateract conditions with the band/lug type tubes? With all that strapping and shielding was the use of bonding materials eliminated?
As for releasing tubes of vacuum, I remember a safe way was to drill a hole in the anode button after making sure it would remain discharged!
