  1. General Dimension Restrictions (flange OD clearance). not based on flow recommendations.
  2. Based on 50% open area. If your particular codes/application requires different - Contact a Fluidtrol
  3. Dealer Calculations performed using 50% open area grate spacing. When 40% and other open area specifications are met - velocities are changed.

Grate width and length dimensions are based on the open grate inside of all support structure. Therefore, add 2 1/2" to grate width and length for box outside dimensions. PVC grate assemblies are 1 1/16" tall and are contained within the drain box height. Water stops extend 2" outside of the drain box perimeter. The height of the water stop is 2" below the grate surface.
