Most Liked Positive Review
Awesome product! The only one i install now.
It has variable speeds, light option, runs quietly and has a condensation sensor to avoid built up humidity/mold! It works with a 3" or 4" duct so can fit everywhere with its low profile. Kudos for thoughtful, practical design and engineering. I have installed one in each of the 4 new bathrooms that i have built in the last couple months. Very happy customers!

THIS DOES N OT FIT WITHOUT SURGERY
The oval portion is 4", not 5" and has to be bent and malformed to work. It only works properly when jammed hard onto the oval duct in the fam, and that interferes with the damper door. It can only be completely sealed from air leakage with caulk. When I inquired to Supply House about other poor reviews, the very rude person on the phone said all reviews were positive. Others have had the same problem. DO NOT BUY THIS OR ANYTHING ELSE FROM THIS LYING COMPANY.

An excellent professionally-made product
This solves the problems of forming and over-taping a home-made piping transition. Very well made and a perfect fit. Pleased to have found this product.

Modification required to use
3" side is set for only metallic sheet metal vent hose. Required severe modification for 3" flex hose. Metallic not plastic.

Would buy again.
Needed this item for a Panasonic FV-0510VSL1 WhisperValue DC Ventilation Fan. Works and fits perfect.

Not oval
You must bend the 4" round to create an oval to fit the Panasonic fan damper so it does not fit exactly. The picture is inaccurate.

Quick delivery at a great price!
I needed a part on short notice and thought I'd never ordered from SupplyHouse before, I took a chance. I'm so glad I did because they shipped the item the same day and it arrived very quickly! Price was also competitive with major retailers as well (actually it was even better!).

Duct adapter
These duct adapters (I ordered 2) are needed for certain Panasonic bath fans. These adapters from Supply House were perfect.

I would buy this product again.
This part was handy to have as my existing ductwork was a 3" duct so this made the install go a lot smoother as the exhaust port on the fan was larger. This adapter saved a lot of time with the install plus not to mention the money to put in all new ductwork!
