The Zurn 12" Floor Drain is a heavy-duty area drain built to handle large volumes of surface water in demanding commercial and industrial environments. With its 12-inch diameter design, it offers reliable drainage for plazas, loading docks, paved courtyards, and other high-flow surface applications where durability and performance are critical.

Key Features

  • Deep Sump Cast Iron Construction – Crafted from Dura-coated cast iron for maximum strength and corrosion resistance, ensuring long-lasting performance in harsh conditions.
  • Integrated Seepage Pan & Bottom Outlet – Collects seepage around drain edges and directs water efficiently through the bottom outlet for effective flow management.
  • Membrane Clamp with Heavy-Duty Tractor Grate – Secures the waterproofing membrane to maintain system integrity, while the tractor-style grate supports heavy loads and resists shifting or tilt under pressure.

Zurn Z512 – 12" Heavy-Duty Drain with Tractor Grate

A 12" heavy-duty area drain featuring a Dura-Coated cast-iron body with bottom outlet, seepage pan, and a combination membrane flashing clamp & frame—topped by a tractor grate designed for wheel loads on decks, ramps, plazas, and industrial slabs.

In technical terms, the Zurn Z512 integrates waterproofing via a clamp/frame and seepage pan while delivering robust inflow through a heavy-duty tractor grate. In plain English: it’s a tough, serviceable point drain that ties neatly into membranes and stands up to carts and traffic.

Installation Highlights

1) Set & Anchor

Seat the drain body at rough elevation; anchor per detail; verify positive slope to the drain across slab or paver bed.

2) Waterproofing Tie-In

Integrate the seepage pan and clamp/frame with the membrane; protect the assembly during pours/overlays.

3) Commission & Maintain

Install/secure the tractor grate; consider -Y bucket where leaf or grit load is high; schedule seasonal clean-outs.

Case Study: Loading Zone Retrofit

A grocery distribution dock struggled with broken tops and ponding after resurfacing. Crews standardized on Zurn Z512 with 4" No-Hub outlets, -TS secured tractor grates, and optional -Y buckets near landscaping. The robust grate eliminated rocking, the clamp/frame simplified membrane tie-ins, and maintenance reported faster draw-down during storms.

Frequently Asked Questions

What is a “tractor” grate, and when should I use it?
A tractor grate is a heavy-duty pattern designed for frequent wheel loads (carts, forklifts, light vehicles). Use it on decks, ramps, and loading areas where impact resistance matters.
Which outlet connection should I specify?
Match your system: No-Hub (NH) for cast-iron, Neo-Loc (NL) for compression fit, or Threaded (IP) for steel. Typical sizes are 2", 3", and 4"; confirm availability on the submittal.
Can I get architectural finishes?
Yes—use prefixes ZB (polished bronze) or ZN (polished nickel-bronze) for finished spaces; base prefix Z is cast iron.
