This black hollow closed-foam seal compresses when the door is shut to seal out water & air. This seal is also placed between the window frame & the trailer wall when the window is installed. The peel & stick adhesive strip is placed on the flat back side. This seal is designed to fill small gaps if fastened to a door, without tweaking the door or the hinges if the door is shut tightly.
The 3/8" wide seal compresses to 3/8" wide & 1/16" tall.
The 5/8" wide seal compresses to 5/8" wide & 1/8" tall.
