Product review (4 stars): Did not fit Broan model 100 CFM, lens 99111410
This did not fit my Broan/NuTone model 100 CFM which is a fan/heater/light combo. The dimensions fit (the picture suggests that it is too small but that is an optical illusion), but the soft square edges would not recede into the space. I should have looked at the lens and found the model #99111410 etched into the side of the plastic BEFORE placing this order and I would have ordered the correct replacement part the first time.  I gave it 4 stars because it's an excellent, sturdy piece but I would like for the description to include the lens models that is can replace.
