Sioux Chief 860-RGS Full Ring Strainer for FatMax Drain, Stainless Steel 304

The Sioux Chief 860-RGS is a full ring and strainer assembly built to fit the Sioux Chief FatMax™ floor drain system, giving plumbers and contractors a way to customize the FatMax™ to the specific needs of a rough-in or retrofit application. The strainer ring is manufactured from Stainless Steel 304, a corrosion-resistant grade well suited to the wet, debris-prone environment found at a floor drain opening. This component is sold as a replacement or upgrade part for the FatMax™ platform and ships one each (1 EA) per package.

Key Features

  • Durable Construction: Made from Stainless Steel 304 for corrosion resistance in wet, below-grade, and high-moisture drain environments.
  • Full Ring/Strainer Design: A complete ring and strainer unit, not a partial replacement component, so it drops in as a full assembly.
  • FatMax™ Compatibility: Engineered specifically to customize and configure the Sioux Chief FatMax™ drain body to the job's specific application requirements.
  • Single-Unit Packaging: Packaged 1 EA, making it easy to stock individual replacement rings/strainers for service calls or new installs.
  • Trade-Ready Finish: Stainless steel surface resists staining and pitting better than plated or coated steel alternatives in constant-wet drain locations.

Technical Specifications

  • Material: Stainless Steel 304
  • Product Type: Full Ring/Strainer for FatMax™ Drain System
  • Country of Origin: China
  • Packaging: 1 EA

Typical Applications

  • Replacement or upgrade part for Sioux Chief FatMax™ floor drains
  • Commercial and residential floor drain rough-in and retrofit work
  • Service and repair calls on existing FatMax™ drain installations
  • Jobs requiring a stainless steel strainer in wet or high-moisture locations

Why Sioux Chief?

Sioux Chief designs the FatMax™ drain system to be configurable in the field, and the 860-RGS full ring/strainer is part of that customizable platform, letting plumbers match the drain to the specific demands of each application. Built from Stainless Steel 304, this ring/strainer is intended to hold up to the corrosive, constantly wet conditions typical of a floor drain opening. Choosing a genuine Sioux Chief replacement component helps keep the FatMax™ assembly working as designed.

Sioux Chief 860-RGS – Frequently Asked Questions

1) Will the Sioux Chief 860-RGS strainer fit any floor drain, or only the FatMax?
It is built for the Sioux Chief FatMax floor drain system only. The 860-RGS is a full ring and strainer assembly made to configure or replace the top on a FatMax drain body, so it should not be treated as a universal floor drain grate for other brands or other Sioux Chief drain bodies.
2) Is the 860-RGS a complete ring and strainer, or just the grate insert?
Complete assembly. The 860-RGS is a full ring and strainer unit rather than a partial piece, so you get both the ring and the strainer and it drops in as one assembly. You do not need to source a separate ring to use it.
3) Will a stainless strainer hold up in a constantly wet floor drain, like a kitchen or washdown area?
The 860-RGS is Stainless Steel 304, a corrosion-resistant grade that resists staining and pitting in constant-wet drain locations better than plated or coated steel. That makes it a reasonable choice for commercial kitchens, washdown floors, and below-grade or high-moisture drain openings.
4) Can I use the 860-RGS as a service replacement on a FatMax drain that is already installed?
Yes, that is one of its intended uses. It is sold as a replacement or upgrade ring and strainer for existing FatMax installations, which covers service and repair calls as well as new rough-in and retrofit work.
5) How many pieces come in a pack of the Sioux Chief 860-RGS?
One each. The 860-RGS ships 1 EA per package, so if you are outfitting several FatMax drains on a job or stocking a service truck, order one per drain.
6) What is the exact part number and manufacturer for this FatMax full ring strainer?
Sioux Chief, part number 860-RGS. That is the manufacturer part number to quote when ordering or cross-referencing the FatMax full ring and strainer in Stainless Steel 304.
