Excellent product, outstanding service!

I ordered belly board for my manufactured home after rodents destroyed the original belly board. Mobile Home Parts Store had exactly what I needed and I received it on time for a reasonable price. I will definitely look to this company again for future needs for my home. Thank you!

Q: do you just go by the length and width of the trailer so if mine is 14 by 70 this is what I need?
A: Yes.
Q: Does it go under the subflooring or under the mobile on the exterior?
A: This goes underneath the mobile home. It is the black belly material that keeps the insulation in. It also helps keep small animals such as rodents out.
Q: How do you secure the bottom board?
A: Use the bottom board tape that can be found in the bottom board repair section of the website.
