I didn’t know that weatherflow also sells an installation kit. Of course one can make it yourself, but this looks like a handy addition for many buyers.
They’re charging twenty bucks for three bucks of scrap PVC ?
In reality they are charging more for the sourcing and assembly of the kit. People are paying for convenience.
Of course. The old adage is true - it’s not a real project unless it takes three trips to Home Depot.
