How to Guide

The parts shown in illustrations (A) and (B) come in one kit with all of the necessary hardware.
Illustration (C) are the Side Rails & are sold in pairs.
Stanchion & Anchor
Instructions for Stanchion & Side Rails (both optional)
To connect multiple Flood Gates together the stanchion set must be used
Determine the appropriate size or mixture of sizes of Flood Gates to fit your openings.
Choosing the correct size Flood Gate:
Flood Gate Size 30"- 35"
Max. Expansion: 39"
Height: 26.5"
Flood Gate Size 40" - 45"
Max. Expansion: 49"
Height: 26.5"
Flood Gate Size 35" - 40"
Max. Expansion: 44"
Height: 26.5"
Flood Gate Size 45" - 50"
Max. Expansion: 54"
Height: 26.5"
The decision must be made prior to installing
the side rails and preparing the opening.
Once you have measured the opening
(D - see ILL D), you must choose
a combination of units
A = Gate Size B width = 3.56” C width = 1 5/8”
The expandable Flood Gate unit should
not exceed 5 inches
The evaluation should be done by a professional engineering consultant.
Prior to fitting the Flood Gate system to any existing structure or pre-construction, a full evaluation of the
structure must be completed to assess whether or not the structure is in fact suitable to withstand the
hydro dynamic and hydro static pressures that occur during a flood situation. This includes evaluating the
force impact of static water load pressures and moving pressures.
