FB77 flash flood doors

These heavy-duty flash flood doors are ideal for building openings, mechanical rooms, passageways and tunnels where a flush threshold and a full perimeter seal is required.

When floodwaters begin to rise, the FB77 is simply swung into place. Side bolts hold the door in place and dual pneumatic seals provide redundant protection on all four sides of the door.

Every FB77 is custom built to exacting dimensions for new or existing construction.

For fast, maximum flood protection of passageways and similar applications, the FB77 Flash Flood Doors are the ideal solution. Hinged panels glide effortlessly into place and dual pneumatic seals are easily and quickly inflated to fully seal the opening.
