Resitrix pipe boot

This is a bespoke pipe boot fitted over a 100 mm pipe protruding a ‘flat roof’. The roof is actually at a slight gradient. Essentially the idea is to fit a discover the pipe and then weld a strip around the pipe. I find that a 50-60mm hole cut into the centre of the disc is sufficient but break the reinforcement at least as wide as the pipe or it’ll make things more difficult. Usually pipes protrude higher but the principle is the same. Enjoy and ask questions.
