Promenade Deck Drain

This Promenade Deck Drain is engineered for placement in roof top recreational and parking decks where the Insulated Membrane Assembly (IRMA) method of waterproofing is used. Protected on top by a 14″ (355) sq. heavy duty grate with combined flashing collar and clamp, this Duco coated cast iron drain securely grips waterproofing membranes without puncturing for a leakproof installation. Underneath the grate is a 4″(100) perforated stainles steel gravel guard that protects drain lines from crushed gravel.
