Question:

I have a 2021 Grand Design 310 Fifth Wheel and I need to replace some of the Rubber Wiper Seal and Bulb for RV Slide Out. It appears to be 3inches wide, buld appears to be 3/4 and it is stapled onto the side wall. They also ran a bead of caulking up the outside of the bulb.Which seal would best fit my needs. I do like the one with 3m tape. Seems the install would be a bit easier. I need 8 2 of seal and it seems all you have is 15 which with less that 6 and would go to waste... any other options?

Hey Dale, it sounds like what you are looking for/at is the Rubber Wiper Seal and Bulb part # SR98FR which is the closest option we have to what you are looking for. I wish we had a better size to match your needs but we do not at this time.
