This self adhesive door seal gasket is for Airstream main doors from 1974 through at least 1994.

 It is installed on the door's flange around the perimeter with the gasket's profile sloping to the edge of the flange.Peel-and-stick adhesive is very strong so position carefully.

The base is 1/2" wide (adhesive is 3/8" wide) and height is approximately 5/8".

24 feet is enough to do almost any vintage trailer door.
