Hey Robert! Yes, the Rectangle Rubber Ribbed Seal # CS43FR can work around your side door on a 6' x 4' utility trailer. It is designed to seal small gaps, typically up to about 1/4" to 3/8", making it a good fit for most properly aligned doors. Since it sounds like the original seal is worn out, it’s a good idea to double check that gap so the new seal will compress properly and keep water out.

What are you typically hauling with the utility trailer?
