Sioux Chief 842-4LNR Adjustable ABS Floor Drain with 6" Round Nickel-Bronze Strainer

The Sioux Chief 842-4LNR is an adjustable floor drain built with a 4" ABS body and finished with a 6" round nickel-bronze strainer. Designed for rough-in installation beneath a finished floor, this drain allows the strainer assembly to be adjusted to match final floor height during installation, making it a practical choice for plumbers and contractors working in slab or wood-frame construction. The ABS body resists corrosion from typical drain-line exposure, while the nickel-bronze strainer provides a durable, long-wearing surface at the finished floor level. This is a trade rough-in plumbing component intended for connection into the drain-waste-vent (DWV) system, not a decorative fixture.

Key Features

  • Trade Size: 4" nominal drain body size for standard floor drain rough-in applications.
  • Durable Body Construction: ABS plastic body resists corrosion and chemical attack common in drain-waste-vent piping systems.
  • Strainer: 6" round nickel-bronze strainer provides a durable, long-wearing finished-floor surface over the drain opening.
  • Adjustable Design: The drain assembly adjusts to accommodate final floor height, simplifying rough-in-to-finish coordination on the job site.
  • Round Profile: Round strainer configuration suits standard floor drain openings in commercial and residential floor assemblies.

  • Body Material: ABS
  • Body Size: 4"
  • Strainer Size: 6" Round

Sioux Chief 842-4LNR – Frequently Asked Questions

1) What pipe size does the Sioux Chief 842-4LNR floor drain connect to?
The 842-4LNR has a 4 inch nominal ABS body, so it ties into 4 inch DWV drain line. ABS to ABS means a standard solvent-weld connection into the waste piping below the floor.
2) How does an adjustable floor drain handle a finished floor height that isn't set yet at rough-in?
That is exactly what the adjustable design on the 842-4LNR is for. The strainer assembly raises or lowers after the body is set, so you can pour or tile to final floor height and then bring the 6 inch nickel-bronze strainer flush without disturbing the rough-in. On a fixed-height drain you would have to get the body elevation right the first time.
3) Is an ABS-body floor drain acceptable for a commercial mechanical room, or do I need cast iron?
The 842-4LNR is a trade rough-in drain used in both residential and commercial floor assemblies, including mechanical rooms, basements and utility areas. The ABS body resists corrosion and chemical attack typical of DWV piping. Where a job spec calls out a cast iron or coated cast body, or where heavy wheel and point loading is expected at the grate, ABS is not a substitute for that spec.
4) Will a 6 inch round strainer cover my existing floor drain opening?
The 842-4LNR tops out at a 6 inch round strainer over a 4 inch body, which suits a standard round floor drain opening. If the drain you are replacing has a larger square grate or an oversized tile cutout, the 6 inch round top will not cover it and you will be patching the floor around it.
5) Can this drain be set in a slab pour as well as a wood-frame floor?
Both. The 842-4LNR is intended for rough-in beneath a finished floor in slab-on-grade and in wood-frame floor construction, in new work or as a floor drain replacement. The adjustable strainer is what makes it work in either, since final floor thickness differs between the two.
6) Why a nickel-bronze strainer instead of plastic or chrome on a floor drain?
Nickel-bronze is the wear surface choice when the grate sits in a walked-on or mopped finished floor. On the 842-4LNR it gives a 6 inch round metal top that holds up to traffic and cleaning above the floor, while the ABS body handles corrosion below it. Plastic strainers scuff and deform faster under the same use.
