getting big tank through the window

[Gary]

I have used suction cups to install some pretty big tripple glazed glass units with excellent results.

The cups that I have were purchased a Princess Auto. They have three cups about three inches in diameter mounted to a triangular handel. We have used two of these to lift tripple glazed windows about four feet wide x six feet high.

I can't remember the exact load rating but it was fairly high on the tripple cup version.
