Softub retro fit fixture

Description

Softub retro fit fixture.
This is a rare retro fit Soft tub vent. Changing the older style 5 1/4” to 6”
with this you can use the newer filters.
I searched everywhere to locate this one . Unfortunately I sold the tub.
It has some modifications to the vent cover, I don’t know why. This is how I got it. It’s on the back and doesn’t show or effect the operation.
I paid 0.00 many are over 200 if you can find them.
please ask any questions.
thanks
