Stick these drip guards above door openings and windows to channel rain, snow, and water away. Also known as gutter rails, they help keep interiors dry and prevent streaks from dew and drizzle. For the best results, stick them onto a nonporous surface, such as glass, metal, sealed concrete, and painted wood. If your installation is crooked, simply peel the drip guard off, adjust, and reapply. The adhesive needs 72 hours to reach full strength.

For a precise fit, cut the drip guard to length with scissors.
