D3C
Hinged Watertight Door With Mechanical Seal
This heavy-duty watertight door is ideal for openings with light
traffic that need to be sealed quickly and easily in the event of
flooding. The D3C exceeds FEMA and NFIP Floodproofing Certification Standards.
Because these doors are engineered for a mechanical seal, no air
pressure or power is needed and maintenance requirements are
minimal.

These doors are ideal for heavy industrial plants, utilities and civic
facilities that must be secured and protected in the event of flooding.
APPLICATIONS — THE D3C AT WORK…
The D3C is ideal for a door that requires infrequent access and
needs to be sealed around the entire perimeter. Common applications include mechanical rooms, auxiliary power units and storage
rooms that must be kept dry in case of flooding. The D3C is virtually
maintenance free.
FLOOD PROTECTION IN SECONDS…
Door size dictates the number of handles/dogs, which are evenly
spaced with stainless steel rollers to all evenly distribute the loads
on the gasket compression. The handles are provided with an “o”
ring seal and two oil-impregnated bronze flange bearings to maintain shaft alignment. When not in the dogged position, the handles
are held in the stored position by disk springs. Each dog has an
adjustment mechanism for ideal seal compression.
