Frost King R534H is a self-stick weatherseal designed to improve energy efficiency and reduce drafts around windows and doors. Made with durable rubber, it forms a tight seal to keep out cold air and moisture. Easy to install, simply unwind and press the adhesive side onto clean, dry surfaces. Cut the excess with scissors or a razor for a custom fit. Suitable for both windows and doors, it can be applied to the upper and lower sashes of windows or across the top and down the latch side of doors.
