I do have a ton of different bulb seals for you to choose from but we don't have any way of knowing what any one particular trailer uses. That said, all you really need to do is look how the existing attaches; flange mount, track mount, c-channel mount, stick-on etc. Then you can choose one from the list attached below after you confirm the length you need as well.

The Rubber Bulb Seal for RV Slide Out part # SR69FR for example mounts in a 3/16" track and measures 15' long.
