150mm plastic duct adapters

We have a home workshop for my partner to refurbish furniture - think of kitchen cabinet doors, cupboards, etc. We fitted a 2M fabric spray booth (she only uses water-based paints) and needed a ducted extractor to keep the overspray dust inside the booth.

We already had an extractor system, so just needed the adapters to connect the 150mm plastic spiral duct to it, then a joiner as the lengths of tube were not long enough to do it in one piece, and then fittings for the booth to connect the duct to and install a sacrificial filter in the booth.
