Zurn Z664 – Cast-Iron Trench Drain

The Zurn Z664 is a modular cast-iron trench drain for continuous surface drainage in high-use hardscapes—ideal for plazas, retail promenades, parking structures, and dock aprons. Its rugged body, secure grate retention, and job-site friendly accessories help from layout to long-term maintenance.

Technical overview: Z664 uses cast-iron channel sections with bolt-down grates, anchoring provisions, and end/outlet components to build straight runs at consistent elevations and slopes. Overview: it’s a tough linear drain that captures sheet flow along facades and joints to keep walk paths drier and safer.

Key Features

  • Modular cast-iron channels — assemble long, straight runs with consistent slope or level grade.
  • Bolt-down grate system — secure seating resists movement and deters theft; easy to service.
  • Anchoring & leveling — provisions help stabilize channels during concrete pours for crisp lines.
  • End & outlet options — components simplify tie-in to site drainage (verify sizing on submittal).
  • Durable construction — stands up to carts, pedestrians, and light vehicular traffic (confirm load class per project).

Where Z664 Excels

Choose Z664 for storefront aprons, pedestrian plazas, parking decks, campus concourses, and dock aprons. Linear capture at thresholds and joints reduces ponding, improves slip resistance, and limits freeze-thaw spalling.

Benefits

  • Cleaner hardscapes — intercepts runoff before it spreads across walking/drive areas.
  • Faster installs — modular sections, anchor lugs, and simple accessories speed layout and pours.
  • Predictable maintenance — bolt-down grates and open channel profile streamline debris removal.

Specifications at a Glance

System: Cast-iron modular trench drain

Grates: Bolt-down; patterns/opening sizes per spec

Sections: Straight channel modules with end/outlet pieces

Anchoring: Provisions for stable, level installation

Load Rating: Project-dependent (confirm per drawings)

Applications: Plazas, retail promenades, parking decks, dock aprons

Confirm grate style/opening, finish/coating, outlet size/type, and load class to match civil and architectural plans.

Installation Highlights

1) Base & Alignment

Establish a stable base, stringline the run, and set channels to design slope or level grade.

2) Anchor & Pour

Use anchoring provisions and bracing during the pour; keep grate ledges free of concrete.

3) Finish & Commission

Install grates with specified hardware, torque per manufacturer, and verify watertight outlet connections.

Case Study: Campus Promenade Rehab

A university replaced scattered spot drains with continuous Z664 runs along building fronts. The linear capture reduced ponding complaints by ~45% during seasonal storms. Facilities teams noted quicker debris cleanouts thanks to bolt-down grates and open channel access.

Frequently Asked Questions

How do I choose a grate pattern?
Match opening size and pattern to use case: heel-resistant slots for pedestrian areas, higher open area for debris-prone sites. Confirm ADA/heel-proof needs where applicable.
What load class should I specify?
Capacity depends on grate selection, embedment, and slab design. Verify the target class (pedestrian, light-vehicular, etc.) on the submittal package.
Can multiple runs tie into one outlet?
Yes—use end/outlet components and branch piping per civil drawings. Provide cleanouts for long runs and maintain channel slope.
