Specifications: The Josam 21500-AER Series is a coated cast-iron drain with a large, polypropylene locking dome. Includes a WEJLOC® non-puncturing clamp ring, large sump with adjustable extension rods, drain receiver and bottom outlet.
Application: Can be used on any sized roof for any type of construction. A large slotted dome ensures maximum free area for quick rainwater drainage while protecting the drain sump and connected piping from debris. Its WEJLOC® compression-flashing clamp holds the membrane or flashing securely to the drain body. Threaded rods attached to the drain body and receiver permit the raising and lowering of the roof drain body to meet the insulation thickness at the required elevation.
