Weatherhead Kits

Create a weatherproof entry point into a building for service cables and telephone lines—these kits have all the supplies you need. The weatherhead has a rounded hood and plastic insulators in its routing holes to protect your wiring from water. The weatherhead is also lightweight, so it’s easy to install. To keep your roof watertight, the roof flashing directs water away from the point your conduit enters.

Aluminum Weatherhead—Made of aluminum, the weatherhead resists corrosion.

NEMA 3R Enclosure Rating—They meet NEMA 3R for protection from falling rain, sleet, snow, and dirt. They also handle light splashing from the side.
