Door Drip Guards
Divert rain and snow away from door openings. Also known as drip caps, these guards are typically installed along a door header.
Anodized aluminum guards resist corrosion better than non-anodized aluminum guards. That means they maintain a uniform finish, even in harsh weather conditions.

Flexible Adhesive-Back Door Drip Guards
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. Made of flexible vinyl, they conform to uneven surfaces and bend along gradual curves, like a windshield. The 3M VHB (Very High Bond) adhesive creates a waterproof seal that withstands any weather as well as vibration. 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.

Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
Galvanized steel has good corrosion resistance. 304 stainless steel is more corrosion resistant than steel and aluminum.
