Sioux Chief 833 NH Ductile Iron Adjustable Drain Finish Line

Sioux Chief 833 NH Ductile Iron Adjustable Drain Finish Line

The Sioux Chief 833 drain finish line is part of the 8332 Series and is built for rough-in floor drain installations where the finished floor elevation has not yet been set. Available in NH no-hub connection sizes from 3" to 4", this finish line assembly lets the installing plumber adjust the drain height AFTER the concrete pour, eliminating the need to guess finished floor height before the slab goes in. The assembly combines a cast iron base adapter with a ductile iron clamping collar, a coring sleeve, a head adapter, and a poly coring plug, with a choice of ductile iron strainers for heavy-duty applications or nickel bronze and stainless steel strainers for pedestrian traffic areas. The adjustable design is covered under Patent #7,735,512.

Key Features

• Trade Size Range: available in 3" and 4" NH connections sized for standard no-hub drain rough-in piping.
• Adjustable After the Pour: the finish line assembly allows the strainer height to be set once the concrete slab is poured, instead of having to pre-set the drain elevation before the pour and finish work is complete.
• Durable Construction: cast iron base adapter paired with a ductile iron clamping collar for a heavy-duty, long-lasting rough-in connection.
• Ductile Iron Strainer Option: ductile iron strainers are available for heavy-duty applications subject to vehicle or equipment traffic.
• Nickel Bronze/Stainless Steel Strainer Option: nickel bronze and stainless steel strainers are available for pedestrian traffic areas.
• Coring Components Included: the assembly includes a coring sleeve, head adapter, and poly coring plug to support the coring process during installation.
• Patented Design: the adjustable finish line mechanism is covered under Patent #7,735,512.

Why Sioux Chief?

Sioux Chief engineers the 833 drain finish line with a cast iron base adapter and ductile iron clamping collar to hold up to the demands of rough-in floor drain installation, while offering a choice of strainer materials to match pedestrian or heavy-duty traffic conditions. The patented adjustable-after-the-pour design gives plumbers and contractors flexibility to set the correct drain elevation after the slab is finished, reducing rework caused by elevation mismatches on the jobsite. Across both the 3" and 4" NH sizes, the 833 Series delivers a consistent, code-compliant rough-in solution for new construction and heavy-duty commercial floor drain projects.
