Larger gaps between RV doors and frames need a bulkier seal. This smooth-face D-seal measures 3/4-by-3/4 inch and sticks with self-adhesive on one side. At 50 feet per roll, one is usually enough for a pair of entry doors. It takes about 30 minutes to apply and maintains its seal through temperature swings.
