This is the tack strip that goes in the channel around the inside of the door and the upholstery would be nailed to. The tack strip is a plastic material instead of the original woven or twisted cardboard. It still fits in the original channel like the original.
Note: This is sold by the foot!
Example: 5 X the part equals 5 foot!
