When space is tight around doors, windows, and vents, this compact bulb seal delivers reliable compression without excessive thickness. The 28-foot roll of polyvinyl chloride won’t crack or split, and the 1-inch width with 3/4-inch depth suits narrow gaps. Single-side adhesive installs in roughly 30 minutes on most RVs.
