As cast dimensions may vary by plus or minus 1/16 inch per foot in critical areas relating to fit, load bearing capacity and drainage openings. Non-critical dimensions may be modified slightly to facilitate proper casting techniques, without notice. Notwithstanding these tolerances, all rings, covers, frames, grates, and curb hoods of the same nominal size are interchangeable.
