STANCHIONS: LAYING OUT THE HOLE LOCATION
STANCHIONS: LAYING OUT THE HOLE LOCATION
An engineer will advise on the most appropriate method of boring the hole. Two popular methods include
(but are not limited to) the use of a high pressure water saw or a diamond faced concrete hole drill.
Use a straight, rigid guide bar (not supplied), cut to the width of the door opening. A guide bar made of
1 ¼” x 1 ¼” x 1/8” (31.75 mm x 31.75 mm x 3.17 mm) angle steel or aluminum is recommended.
Mark a line across the guide bar at appropriate intervals (See illustration I in
red
). These marks represent the
centerline spacing of the holes to be bored. The intervals depend on the mix of Flood Gate units you
identified at the planning stage as the most suitable.
Lay a carpenter’s square on the floor against the inner surface of the guide bar and mark a vertical line. Then
measure 3in from the guide bar & mark a horizontal line. These lines become the center of each bored hole.
This illustration is an Example of an opening of 200in for (A). Using 5 Flood Gates, each stanchion,
or dimension (B) is positioned at their respective center lines.
CAUTION: Whether or not you opt to use the Side Rails, the 3 in. / 76.2 mm centerline dimension of the
bored Stanchion holes must always be maintained from whatever surface the back face of the Flood Gate
comes into contact with on the opening.
NOTE: The 3in/76.2mm set back dimension to the center line of the bored holes
is critical to ensure proper alignment of the Flood Gate panels.
