Proform Fan Blade Switch?

Can Proform and Flex-A-Lite Fan Parts Interchange?

My Proform 15" electric fan came loose the other day and hit into my pullies shredding my blades. Rather than buying another fan for $130+, I looked at what Summit had to offer. Flex-A-Lite makes replacement blades for their 15" electric fan. Both the Flex-A-Lite fan and the Proform fan look identical. Does anyone out there know if the Flex-A-Lite blades will bolt up to the Proform shroud if I were to drill out the rivits and replace with tiny bolts and nutts?

Anybody Have Any Input?

Blades just arrived today. They match up beautifully. Here's the tip of the day- if you have a Proform electric fan and your blades are broken, you can indeed buy the 15" Flex-A-Lite replacement electric fan blade and put them on. $30 from Summit. Good thing to if your happen to find one in the junk yards! They just slide on the fan motor shaft and are retained by a set screw.
