This watertight door is ideal for openings with frequent traffic that need to be sealed quickly for flood mitigation.

Because these doors are engineered with mechanical seals, no air pressure or power is needed and maintenance requirements are minimal.

Every D3DQA is custom built to exacting dimensions for new or existing construction to maximize flood mitigation. For existing openings, frame is mounted to building with expansion anchors; for new construction, the frame is poured in place.

#### COMPLETE FLOOD PROTECTION WITH THE TURN OF A HANDLE

Simply closed the door and turn the handle ¼ turn to securely seal the door on all four sides. The standard model protects to 25’ head (higher heads are available).

#### FLOOD MITIGATION— THE D3DQA AT WORK

The D3DQA is ideal for Water Treatment Facilities, Sewage Treatment Plants and Pumping Stations; as well as mechanical and equipment rooms in any critical facility.
