Slim Duct used to make a 4" riser for mini split condensers that was 78" long,
that item is no longer available.
Who knows where I can find such a critter ?
Sounds kinda weird I know, but the request has been made for me to find them again. I need a couple of them at least 6" long.
Can not use treated 4X4 's .Must look nice for the customer.
