I have now bought this twice, for two different homes, and continue to have high praise. Most recent install below.
1) I bought this fan again, after initial great success, to replace a ~30 year old Broan fan with a different mounting system than this fan has by default. As another poster shared, the mounting screws are REVERSIBLE on this fan, which I did reverse to install fan in a similar configuration as existing fan, with the motor now mounted up into the ceiling, as opposed to default configuration to mount fan down into a corresponding bracket (which my second install didn’t have . See pics.
As other reviewer recommended, it may be easier to buy some 3" 6-32 bolts to make this connection a little longer when flipping the mounting bolts - mine just barely worked though. Highly recommended again!
2) ORIGINAL review
This truly is a universal fan for one simple reason - the electric motor axle comes pre-scored to allow you to trim to size for your particular branded housing.
I particularly bought this fan to replace a >40 year old Broan 660 series bath fan (664/665/666 fan- see housing pic). Despite having originally attempted to buy a Broan-branded fan, and despite Broan being very good about maintaining identical parts/sizing over many years - I could not find a fan that was labeled as matching my Broan series. I quickly discovered no one makes a Broan 660 series fan anymore, because the vintage Broan 660 series bracket is approximately 2 inches between the mounting hardware, versus the now-standard 1.87 inches centered between the mounting hardware.
To make this work for my fan, I simply had to take a power drill and enlarge the mounting bracket holes to make this fan’s mounting hardware work.
Given the vintage nature of my fan housing and some peculiarities to this Broan series, it took me a bit longer to swap fans than your normal modern switch out - between widening the bracket holes, cutting the electric motor axle to size, messing with the configuration of the mounting brackets (the fan housing bracket is supposed to go closest to the electric plug, as not depicted), the electric cord being slightly shorter than was used in the 1970s (requiring messing with mounting a few times until figuring it out), and figuring out the orientation of the fan to exhaust in my housing (the flat side of the fan should be facing you after-installed, as not depicted), I probably spent 2-3 hours total on just swapping the fan. All that being said, this buy saved me serious $$/time by not having to replace the entire housing in the attic, and this fan, along with a new Broan-branded grill, makes my setup brand new and ready for another 40 years.
A few general notes for bath fan replacements - if you find insulation inside your fan housing, you likely have a more serious issue (your fan likely vents directly into the attic, or alternatively you have a hole in your exhaust line); if there are gaps between the drywall and the housing, tape it up to ensure all moisture goes through your new fan to be exhausted; and make sure you test that your fan actually exhausts (as opposed to installing it backwards by accident) by putting a piece of toilet paper up against the grill once you’re done.
