Hey Guys.....You want to make it even easier......here is the new screen
Fan-Tastic Pop’n Lock Screen - Product - Camping World from Fantastic Fan. They come two to a pack and are only about $14.00. You remove the 8 screws from the old screen and pop in the new one. The other thing it tells you is that the fan blade is held on by a single allen screw on the side of the fan blade.....I think it's 5/32. You loosen it and the blade comes off for thorough cleaning.
I really like the snap off screens, my bad neck would get sore unscrewing the 16 screws between my two fans.
