Rudy, I installed one of those seals on our
Scamp 13. It appears to be the same as the
Scamp door and frame for installation purposes. You glue the seal on the door frame with the little flange pointing outward, away from the edge of the opening, That little flange seals against the door's edge. In theory, the air pressure when rolling down the road forces the flange tighter against the door as you speed increases. Before you stick the seal in place; try the placement out by closing the door on it. Make sure the little flange is compressed between the door and frame. Once you determine the location peel the tape back in small sections and stick it on.
I hope it works as well for you as it did for me.
