The lower bag on my King dust collector came with a plastic viewing window in it. That was a great idea (initially) because you could see how much it had filled up.
THEN!!! One day I went to where the collector was only to discover chips all over the floor..The window had let go on one side and everything was being blown out! I tried a temporay fix using duct tape..It worked for a while until the adhesive dried out and then it separated,,same thing again. Next In tried some of that metal duct take because it had amuch better adhesive.
This evening I discovered it too had let go!
I liked the window idea, however it clearly isn't reliable and tomorrow I'm taking the bag to have a piece sewed in where the window was. I'll ask to have something put between the materail to ensure it's sealed.
What a pain!! And what a mess!! Must order areplacement bag in the meantime (without awindow!!!)
