I have 4 older Doyle vacuums that someone decided they needed the stainless domes more than I did! I was going to replace them with the plastic style. Doyle sells them but the color doesn't match my theme that well. They mount with bolts through the bottom sides of the dome. Do other brands mount in a similar fashion? Are other brands similar in diameter? I looked at the ones offered by Kleenrite for IVS, Ginsan, and JE Adams but wasn't sure if they would fit. Any help would be appreciated.
