The Zurn Z541 12" heavy-duty drain comes with a Dura-Coated cast iron body with bottom outlet, seepage pan, and combination membrane flashing clamp and frame for anti-tilt heavy-duty slotted grate with suspended polypropylene sediment bucket.
The standard Z541 grate has slot openings of 3/8" wide, which qualifies it as ADA compliant when the grate is positioned so that the slots are perpendicular to the primary flow of traffic. For a grate to be heel-proof, it must have a slot width of 5/16" or less, so the -HP option should be specified when a heel-proof grate is required for this drain.
