AC Duct Puller
This is a duct puller. (or part of one) A friend who works for an air conditioning / heating company wanted a faster way to lay heating flex duct in hanging ceilings. He told me the problem and this is what i came up with. The sections are 5 feet long and the couplings are 6" long (or more). This will enable my friend to lay the duct in a hanging ceiling by only removing two ceiling tiles. The beginning of the run and the end of the run, plus it is now a one man job instead of a two man job. A nylon cord through the pipe sections pulls the duct over the length of the assembled sections all in one operation.
