D3DQA | Quick-Acting Watertight Door with Mechanical Seals

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.
