Measure the clear opening width and height, then add 2 inches for side-seal compression. Our engineers verify dimensions during the site survey process. Gates over 8 ft require mid-span reinforcement to meet ASTM E330 deflection limits.

Yes—modular gates can span adjoining doorways up to 12 ft using coupler plates. Each segment retains independent seals, simplifying replacement. See Modular Flood Barrier specs.

At least 3 inches of unobstructed vertical clearance ensures full gasket compression and quick deployment. Trim decorative thresholds as required.

Height = Design Flood Elevation (BFE + 1 ft freeboard) – finished floor. Our software calculates optimum height for each zone (Sarasota, Naples etc.).

No—panels under 80 lb include recessed handles and assisted clamps. Larger assemblies use counterbalanced hinges or motorized lifts.

±1 mm tolerance on width, ±2 mm on height yields full seal. Even small deviations can halve pressure resistance, so professional measurement is recommended.
