I am looking for dimensions and hydraulic capacities for a trench drain grate Neenah 12" R-4993-CAB, Type A grate. Is this data available without calling Neenah?
yep, that's it but no grate (open area) dimensions or hydraulic data. I was able to get the hydraulic data for the grate by emailing Neenah, it is not on the website. Luckily they are very responsive.
