Window Duct Kit to Backdraft Damper Adapter

I needed an adapter to fit from my window duct kit to the damper to avoid outdoor air intake. Intended for use with HOXHA Window Duct Kit and FRESH SPEED 4-in Backdraft Damper:Window Kit: https://www.amazon.com/dp/B0DQTJ292BDamper: https://www.amazon.com/dp/B097DRMC48 Features a lip to engage over the window duct kit with slots that can be used to pry off if really needing to removed after it is installed. 4" aluminum ducting goes over the other end of the backdraft damper. I suggest the AC Infinity (I also use their CLOUDLINE A4 inline duct fan).Ducting: https://www.amazon.com/dp/B07WRDTX4CInline Fan: https://www.amazon.com/dp/B09FYK6Z3R I also have some vent netting to mitigate any bugs getting in. The window kit already has weaving to prevent birds, but that was not my only concern. I may change this to be on the exhaust of my inline fan.Vent Netting: https://www.amazon.com/dp/B0B7HXBR75 I hope this helps someone out or provides any ideas. Please also check out my window locks a
