Josam 22010 Roof Drain Sump Receiver
The sump receiver sits on top of the roof deck to receive the drain body. It essentially creates a flat surface for the drain to sit and sump into the roof.
Used on mid-sized roofs of any construction where a medium-sized drain is required. Flashing clamp holds the membrane or flashing securely to the drain body. A medium-sized beehive dome provides ample drainage for smaller roof decks and intercepts debris.
