Josam 24040 Roof Drain - Composition Deck Flange and Super-Flo Grate

Used on promanade roof decks or anywhere that an elastomeric or liquid applied waterproofing is to be applied underneath a 2" pour of concrete or asphalt. Wide deck flange provides proper area for bonding of waterproofing material and distributes the drains weight over a broad area for positive support. Mid-sized round medium-duty Super-Flo grate assures rapid drainage and stops debris from entering the drain and pipe system. The 2" extension supports the grate at the proper finished deck level.
