The adapter is designed for a 4" duct and the fan is set up for that size for best operation.

This is NOT a small, 4" diameter duct. It is 6" diameter, so some installations will require enlarging both duct and penetration through the wall.

Hi, duct size for SIG110H is 4 inches. We will check with Home Depot to provide duct size information on the product page.

Rated 4.6 out of 5 by 5 reviewers.
Rated 4.0 out of 5.0 by Works great...once you figure out the wiring. Installation was fairly straightforward, but wiring was another story! The wiring diagrams leave a lot to be desired. The product description talks only about single switch operation, but the wiring diagrams in the manual are for a two switch application only. Pretty confusing, but three calls to tech support straightened it out...I think. It's working, but I'm still not sure it's correct. September 22, 2015
Rated 5.0 out of 5.0 by Excellent Bath Fan Buying another identical unit for the main bath. Very happy with the first fan, installed in master bath during a major remodel 4-5 months ago. One can bearly hear the fan operating when on 50 cfm. Still very quiet when it kicks on high speed, such as when taking a hot shower. This fan efficiently removes moisture, keeping the room from ever steaming up. Just walk off, and fan will automatically decrease speed to your preset cfm when humidity drops to your selected value. Price has also dropped about 15%. One word of caution -- I had access to attic above the bath, so installation was pretty straight forward. Needed to run duct through stucco wall, and electrical hookup was simplified because removing medicine chest gave access to bath switches and wireing. March 14, 2015
Rated 4.0 out of 5.0 by Overall - This is a great upgrade fan. Pros: Fan is super silent Much improved air flow Adjustable humidity sensor Installation was straight forward (other than the additional switch requirement) Cons: Knowledge that you need an additional switch for the humidity function would have been a benefit from the start if you are doing an upgrade from a non-sensor model. Recommend: Check out the air vent setup before purchase, as all new fans are slide venting, my old fan was top venting, so I also need to change out the air vent to accommidate the new position.

Rated 5.0 out of 5.0 by Excellent fan, very quiet, work as advertised! The fan is very quiet as advertised, installation as directed however I had trouble with the CFM setting, I had wired the fan direct to power without being switched and it ran constantly rather than just when moisture was in the air. I called Delta and was helped immediately by a very professional individual and he told me to turn off the CFM setting. The fan works perfectly. Great product and GREAT support from Delta.
