1" Bulb Seal with Fins

Part Number:
In Stock In Stock


This seal features a rigid "C Channel" section that slides onto the track located on the wiper seal. Its main function is to seal against the RV when the slide-out is closed - protecting your RV from extreme weather and pests. Unique fins help prevent side-flop when compressed and increase the contact surface size at the same time. An excellent upgrade to existing weatherstripping for a more complete seal. It can be used to upgrade just the top seal of a slide-out to add even better weatherproofing. Seen on many new trailers.

Designed to easily slide into place, it is used primarily with the wiper and track part #’s 70-3884-265, 70-3883-265, or 70-3835-265 to complete a slide-out seal. This part can also be used in conjunction with part #70-4120-265 to provide additional sealing options (these parts are sold separately).

Note: When purchasing by the foot, select the number of feet you want in the quantity box and it will be sent in one continuous piece. (Possible exception for bulk orders, where it will be shipped in the longest pieces possible.)
