On the specification page it mentions a thickness of 6,98 cm (2.75"). Is this the size for the tube/skirt or for the upper body? If not, what is the size of the steel tube/skirt?
The steel tube is just a hair under 2 3/8" in diameter.
So, if you’re asking to get a hole saw to cut a hole in a lid for a container, I’d get the 2 1/2" hole saw (and edge the hole with some electrical or duct tape to get a really good seal).
Thanks! That’s exactly what I wanted to know! This specification needs to be complemented on the spec’s page.
