Zurn Z676 – 13" Extra Heavy-Duty Drain

A square-top, extra heavy-duty area drain built to handle high loads and high flow—ideal for plazas, loading areas, industrial floors, and exposed decks.

The Zurn Z676 combines a Dura-Coated cast-iron body with a bottom outlet, seepage pan, and a vertically adjustable four-position frame that accepts a Duresist extra heavy-duty loose slotted grate. In plain terms: it’s tough, serviceable, and designed to move water quickly while standing up to traffic and abuse. (Specs per Zurn submittal.)

Key Features

  • Square top, extra heavy-duty grate (Duresist) for high-load service.
  • Dura-Coated cast-iron body with bottom outlet for longevity and straightforward tie-in.
  • Seepage pan and four-position adjustable frame to dial in finished floor height.
  • Multiple outlet sizes & types: IC, IG, IP, NH, NL in 3", 4", and 6" (verify project submittal).
  • Top material options via prefixes (cast iron standard; bronze or nickel-bronze tops available).

Applications

Specify the Z676 for industrial floors, loading docks, plazas, garage levels, and high-traffic areas where durability and service access matter. The square top suits grid-like slab layouts and joint patterns, while the adjustable frame makes finish work simpler.

Why it’s a fit

  • Handles impact and wheel loads typical of carts, forklifts, and vehicles.
  • Adjustable frame helps align with tile, pavers, overlays, or new surfacing.
  • Seepage pan assists with sub-surface moisture management around the drain opening.

Case Study: Distribution Center Apron Upgrade

A distribution center had repeated ponding and grate damage at loading-bay aprons. The retrofit standardized on Zurn Z676 drains with 6" outlets and secured Duresist tops. After one rainy season, maintenance logs noted faster runoff capture, fewer freeze-thaw edge failures, and easier seasonal clean-outs thanks to the adjustable frame and sediment-capture accessories.

Frequently Asked Questions

What does “extra heavy-duty” mean here?
The grate and body are designed for higher load environments (e.g., vehicle and equipment traffic) compared to medium/heavy-duty drains; see project specs for required load ratings.
Which outlet connection should I choose?
Z676 offers Inside Caulk (IC), Inside Gasket (IG), Threaded (IP), No-Hub (NH), and Neo-Loc (NL) in 3", 4", or 6" sizes to match your piping and install preferences.
Are alternate top finishes available?
Yes. Prefix options include cast iron standard, with bronze or nickel-bronze top assemblies available when aesthetics or corrosion resistance are prioritized.
