What is the term for a rain-tight device at the top of a service raceway?

Explanation:
The rain-tight device at the top of a service raceway is called a weather head. It provides a weatherproof entry point for overhead service conductors into the building’s service raceway, sealing the conductors and allowing a drip loop to shed water. Caps are just covers, not the intended entry device; glands seal around individual cables entering a conduit or enclosure but aren’t the top raceway entry; and a junction box is for splices, not the top-of-raceway transition.
