Customer Questions & Answers

belt size for attic fan

You have a bunch of belts for attic fans, but the listing does not show the size. You have to click on each one to find the size. This takes forever. Can you help me? The broken belt is 54 1/2 inches according to my measurement. I found one that says 55. Will that work or do I need the exact size?
Asked by: steve
Yes. You move the fan back and forth so the half inch slack won't matter.

Need to replace attic fan belt (4L490 DEMCO 21)

Asked by: Monkey
The fans are adjustable so the belt is considered a standard for whole house fans
