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. 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. Please ask any questions. This item is in the category “Home & Garden\Yard, Garden & Outdoor Living\Pools & Spas\Spas & Hot Tubs”. The seller is “airerescue” and is located in this country: US.
