What you want to do is measure the access hole for your heat duct register, and get one that fits the hole size. For example, if it was 4" x 10" you'd use the Dampered RV Floor Register # 37202-29175, or if it was 4" x 8" you'd use the Dampered RV Floor Register # 37202-29155.

I have added a link below to our entire selection for you which you can filter by size.
