The ceiling in our Scamp
has a non-electric crank-up vent (no fan) and it measures approximately 17x24 (or close to that). I'm finding that all the new 3-speed electric fans seem to be 14x14. Is 14x14 the only size available? I'm wondering if there's one available for the size hole I have, or will I have to close the ceiling and cut the new opening for the 14x14 fan? If that's what I need to do, then that's what I need to do. I just wanted to see if there was an option that fir the current hole. I do not know if the previous owners cut that larger hole or if it came that way. Thanks for the help!
