The Zurn Z512 is a robust, 12-inch diameter area drain designed to manage substantial surface water in commercial and industrial settings. Engineered with durability and drainage efficiency in mind, it’s well suited for plazas, loading areas, paved zones, and other high-flow surfaces.

Key Features

  • Deep Sump Cast Iron Body: A Dura-coated cast iron body provides strength and corrosion resistance for long service life in challenging environments.

  • Seepage Pan & Bottom Outlet: Incorporates a seepage pan to catch edge water flow and routes collected water through a bottom outlet for effective drainage.

  • Membrane Clamp & Heavy-Duty Tractor Grate: Uses a combination membrane flashing clamp and frame to secure waterproofing, while the tractor-style grate handles heavy loads and resists tilt.

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. 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.
