Yes. There are all kinds of options to mount this fan. If you pick up a roll of plumbers metal strapping, or metal pipe mounting strips (look in the plumbing section) you can use sheet metal screws to create new mounts (i.e. hanging within a suspended ceiling.

I would recommend using #10 self taping sheet metal screws or bolts. Lots of room on this fan housing to attach alternate mounts without interfering in function of fan.
I found that I could also increase room to work by using tin snips to modify the housing so I could get a ratchet on a mounting bolt head. Read Less

This unit can be installed in a suspended ceiling, using three wires connecting the outer housing to the stucture above the suspended ceiling. The included printed instructions show a picture of a typical installation of this kind.

Answer: 
Thanks for your interest in our products. We offer an up-date kit, but not one with a light. Because the unit you currently have is an exhaust fan only, you would have to remove the old housing to install one with a light. Our units are all U.L. listed. You can not put a fan/light combination unit into a housing that was designed for just an exhaust fan. Call our Technical Support Department at Read More

Rated 3.6 out of 5 by 38 reviewers.
Rated 5.0 out of 5.0 by Great Fan Upgraded save power and sound lower VERY GOOD PRODUCT I LIKE IT. April 29, 2016
Rated 4.0 out of 5.0 by Quiet, moves air well I bought this to replace an old Broan, which has had a couple of replacement motors over 20+ years. I like the fact that it's pretty quiet and moves more air than the previous fan. Installation was a bit tricky due to falling insulation, and the output piece doesn't seem to snap into place, so I used aluminium tape to secure it. Taping the unused holes in the metal box is a good idea, to keep air from venting into the attic surrounding it. February 4, 2013
Rated 4.0 out of 5.0 by great for the money Easy to install as replacement fan in home. Good value, quiet running. October 29, 2015
Rated 2.0 out of 5.0 by Works as intended, but! Yes this fan does a decent job in doing what its supposed to do and that's exhaust air. Its easy to install however it is very loud to me. Why can't they make these things a little quieter? Why must one pay several hundred dollars in order to get a quieter fan? Oh, and note that the installation brackets don't come with it, you have to pay twenty dollars for them. August 30, 2015
Rated 5.0 out of 5.0 by working excellent so far I purchased this fan to replace a 60cfm bathroom fan. I had already upgraded my existing fan with a nutone 690nt retrofit kit but was still having problems with mildew in my bathroom due to poor ventilation. I installed it very easily - took about 30-45 minutes. The reason it was so quick to install was because I had access to the attic and could easily remove the old one and drop in the new one. After installing the fan I really didnt see any difference. After doing some research I found out that the ventilation duct can severely reduce the performance of the fan. I had connected this fan to my existing 3 inch duct using a converter piece even though the fan has a 4 inch blower output. So I returned to HD and bought 4 inch enough semi-rigid duct to replace the ductwork. This was very easy as I have access to my attic and the duct simply vents to one of my existing roof vents - ie I didnt have to change a roof vent or anything. After replacing this ductwork, the performance was much much better. Hardly any condensation on the mirror with a fairly steamy shower. In my research I found the rigid aluminum duct tubing is best for air flow - this not ideal for a couple reasons. Number one, it's expensive. Number two, if you're like me and need to route the duct throughout ceiling joists, it will be complicated to buy the appropriate elbow joints and then cut the tubes in correct length. The flexible tubing (similar to a dryer exhaust duct) is the worst as the corrugated like edge leads to turbulence which restricts air flow. It also makes the diameter smaller because unless you have stretched it to its entire length, the extra will go into the tube lumen as it collapses. So the compromise is semirigid tubing which is flexible but does not restrict the lumen size and also the interior wall of the duct is fairly smooth compared to the flexible ducting. July 22, 2015
Rated 2.0 out of 5.0 by Works well but Hums...... Mounted this fan to a 2x6 as recommended used 4 screws not two nails and it still hums! Also used a 90 bend with proper duct tape (aluminum) and 8ft. of 4" flex hose to the roof vent. Noticed the box itself does not seal well venting both up and down. If I were to do this again I would have duct taped the whole box and plastic fitting very well before install, may have prevented hum and backdraft? I would not recommend this product for first time installers since it needs more TLC than the instructions call for, if you read this and do buy this product follow some of my tips it will cut you some time and headache. April 3, 2014
Rated 5.0 out of 5.0 by a good fan this fan is easy to install, is sufficiently forceful and has a quiet run March 25, 2015
Rated 4.0 out of 5.0 by Good quality Unit is several years old. I have replaced the motor once. February 6, 2015
