What we did on one of our 2645 terminals was the hot wire method. We then
attached the "implosion" window to the inner of the case.
BTW is it really an implosion protection? I don't think so because since
the 60s, practically all CRTs have a so-called "integral implosion
protection" (thick glass on the front and metal band around the edge). I
think it is just an anti-glare filter glass. OTOH American CRTs may be
completely different in this aspect compared to European ones.
