This is a heavy duty frame and grate system furnished in gray iron. It meets ASTM-A48 Class 35-B requirements. It provides superior durability. Neenah recommends project designers avoid the use of light duty trench installations because it is likely that applications will be subjected to heavy delivery traffic at some time. The use of a site could be changed to heavy duty use patters at some unanticipated future date.
