Used in flat roofs and decks designed as parking decks (vehicles traffic) or promenades for recreational (foot traffic). Large square grate provides sufficient free area for proper drainage with narrow slotted openings for pedestrian safety and to intercept debris.The Flashing (V-Shape) clamp holds flashing and roofing materials to the drain body without puncturing. The fixing collar allows aligning the square drain with the square tile or a brick pattern (rotating the frame). Seepage openings are located above the water proofing membrane to recieve any seepage from around the drain and to direct such seepage into drain body.
