I'm looking for the best option to connect 5" flex duct to MM CU300 120mm ports.

I need to move the hose around frequently, one hose moved between the lower saw and shaper ports, and the second hose between the planer, jointer, and shaper hood.

All MM ports are 120mm (actually they measure <120mm...).

Any good ideas for a quick disconnect fitting that has proven to work on this machine? I'm trying to finalize my ductwork design so I can actually turn on some new machines that have been sitting in the shop for a month unused .
