Sioux Chief 923-2326C00 Deep Box Flange, 1-1/2" IPS Chrome-Plated Steel

Sioux Chief 923-2326C00 Deep Box Flange, 1-1/2" IPS Chrome-Plated Steel

The Sioux Chief 923-2326C00 Deep Box Flange is a 1-1/2" IPS rough-in flange built for installations that require extra depth behind the wall or floor. Constructed of chrome-plated steel, this deep box flange delivers a durable, corrosion-resistant surface for exposed rough-in connections, while its sure-grip design is engineered to hold a secure fit as the assembly is set and tightened during installation. The 1-1/2" IPS (iron pipe size) connection is sized to mate directly with iron-pipe-threaded rough-in hardware, and the deep box profile gives plumbers and contractors the extra reach a standard-depth flange cannot provide when a rough-in box sits further back in the wall or floor cavity. It is intended for professional installation as part of a larger rough-in assembly, not as a stand-alone finished fixture.

Key Features

• Trade Size: Sized for 1-1/2" IPS (iron pipe size) rough-in connections, matching the threaded hardware used in deep box flange assemblies.
• Deep Box Profile: The deep box design provides the additional depth needed for recessed rough-in box installations, reaching connections that sit further back in the wall or floor than a standard flange can accommodate.
• Durable Construction: Chrome-plated steel construction is built to resist corrosion and wear on exposed rough-in hardware, holding up to repeated handling on the jobsite and through the life of the installation.
• Sure-Grip Fit: The sure-grip design is engineered to hold a secure, stable connection through the rough-in and finish stages of installation, reducing the chance of the flange shifting once it is set.

Why Sioux Chief?

Sioux Chief builds rough-in plumbing hardware to hold up behind the wall and under the floor, where a callback means tearing out finished work to make a repair. The 923-2326C00 deep box flange carries that same approach: chrome-plated steel construction paired with a sure-grip fit gives plumbers and contractors a rough-in component they can install once and trust through the life of the installation. Packaged 100 to a carton, it is sized for the volume that professional rough-in crews and distributors need on hand for repeat installations.
