Sioux Chief 833-63NR 3" Finish Line Adjustable Floor Drain, Cast Iron Base

Sioux Chief 833-63NR 3" Finish Line Adjustable Floor Drain, Cast Iron Base

The Sioux Chief 833-63NR is a 3" Finish Line adjustable floor drain built for behind-the-slab rough-in work. The assembly pairs a cast iron base adapter with an ABS clamping collar, coring sleeve, and head adapter so plumbers can set, seal, and finish the drain to the correct floor elevation after the concrete is poured. This configuration is designed for connecting to cast-iron drain piping in commercial and residential concrete floor applications, giving the installer an adjustable, code-familiar rough-in assembly rather than a bare fitting.

Key Features

• Trade Size: 3" drain body sized to connect to 3" drain piping in the rough-in.
• Cast Iron Base Adapter: Rigid, durable cast iron base adapter forms the primary connection point to the building drain line and anchors the assembly in the slab.
• ABS Clamping Collar: ABS clamping collar secures the waterproofing membrane and works with the head adapter to set the finish elevation.
• Coring Sleeve Included: Coring sleeve is used to core an accurate, properly sized opening through the concrete slab for the drain body during rough-in.
• Adjustable Head Adapter: Head adapter allows the strainer assembly to be raised or lowered so the drain lands flush with the finished floor.
• Round Strainer Configuration: Finish Line R&S configuration is fitted with a round strainer top for the finished floor opening.
• Two-Stage Rough-In Design: Cast iron base is set early in construction while the ABS collar and head adapter are finished out later, reducing damage risk to the strainer during the build.

Why Sioux Chief?

Sioux Chief builds the 833-63NR Finish Line drain around a cast iron base adapter, ABS clamping collar, coring sleeve, and head adapter so contractors get a complete, adjustable rough-in assembly instead of piecing one together from separate parts. The clamping collar and head adapter give plumbers the flexibility to set the finished drain height accurately after the slab is poured, and the cast iron base gives the assembly a rigid, durable connection to the building drain line, making it a practical choice for professional floor drain rough-in work.
