Floor Drain Strainer: An Overview

The Floor Drain Strainer pairs a Dura-Coated cast-iron drain body with an adjustable, secured round strainer head to deliver a clean finished look, dependable waterproofing, and easy access for routine service in showers and other interior wet areas.

In technical terms, this assembly includes a cast-iron body with bottom outlet, a combination invertible membrane clamp, and an adjustable collar with seepage slots beneath a light-duty round strainer. In plain English: it locks the membrane in place, lets trapped moisture weep safely, and sets the strainer flush to tile, terrazzo, or resin floors.

Why Pros Choose the Floor Drain Strainer

  • Rugged build — Dura-Coated cast iron with a bottom outlet handles daily use.
  • Reliable membrane tie-in — the invertible clamp and adjustable collar form a tight, repeatable seal.
  • Weep protection — seepage slots move incidental moisture under the finish into the outlet.
  • Clean, secure top — an adjustable, secured round strainer stays aligned and resists tampering.
  • Finish flexibility — commonly furnished in polished bronze or polished nickel bronze to match trim.

Best-Fit Applications

Ideal for showers, locker rooms, hospitality restrooms, education/healthcare cores, and amenity spaces. The round strainer complements patterned floors, and the secured head streamlines routine cleaning.

Benefits (Plain English)

  • Better-looking installs — dependable tie-in and weep paths help reduce perimeter staining.
  • Faster turnover — the adjustable head sets final elevation flush for a smooth finish.
  • Service-ready — a secured strainer prevents loss and speeds maintenance.

Frequently Asked Questions

What’s the advantage of the invertible clamp?
It creates a consistent, tight seal to the membrane so the drain remains integrated with the waterproofing even after height adjustments.
How do seepage slots improve performance?
They provide weep paths that move incidental moisture under tile/coatings into the outlet— helping prevent edge discoloration at the drain.
Which outlet styles are typical?
Most projects specify 2″, 3″, or 4″ in No-Hub, IP threaded, Neo-Loc, or IC/IG. Confirm exact combinations on your submittal.
