I am using a model QTHB1 to replace a smaller fan with a larger nutone but I do not have access to attic
the old cfm 50 was attached to one ceiling joist with one screw....the ceiling joists are 24 inches apart...I want to install from underneat ...making the ceiling opening just enough wider to accomodate the larger nutone.....
Guestion.... can the QTHB1 be used to used in this way ??
Thank you for your question on the model QTHB1 exhaust fan hanger brackets. The QTHB1 is designed for select exhaust fans and are designed to be placed on the unit housing before installation in the ceiling. You cannot use these hanger brackets and select exhaust fans to install from below in a finished ceiling. You would need to have access from an attic or crawl space above to use these. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.

length of hanger bars
my ceiling joists are only 12.5" apart so your hanger bars are too long at 13". do you sell a smaller set of hanger bars and where do I get them?
Thank you for your question on the exhaust fan hanger bars. Our hanger bars are all designed to be used with either 16” or 24” on center joists. We do not have a smaller set of hanger brackets for shorter distances.
