What weight will the grates handle?
Weight loading on the grates should always be a consideration. In the floor drain catalog section either in the title or sub-title, a reference is made to light, medium, heavy or extra- heavy. This can be referenced to catalog page 2-04 of the current Smith “Yellow Pages” catalog. These four categories are explained and weight loads specifically noted. The load rating categories are in accordance with the ANSI/ASME Standard governing floor drains. If in doubt about a particular drain, contact Smith’s “Sales Engineering Department”.
