The SIOUX CHIEF 696-7 is a one-hole box designed for use with drain, waste, and vent (DWV) pipe installations. This box provides a clean, code-appropriate mounting solution for routing 2-inch DWV pipe through wall framing and structural cavities. It is used in residential and light commercial plumbing rough-in work where a single pipe penetration point is needed. Licensed plumbers and rough-in crews rely on this type of fitting box to maintain consistent pipe alignment and to meet inspection requirements for DWV system installations.
This box is suited for new construction and remodel applications where 2-inch DWV pipe must pass through a single-gang stud bay or framing cavity. It is compatible with studor mini-vent and similar air admittance valve assemblies that require a dedicated enclosure during rough-in. The 696-7 is the box-only component and does not include additional fittings or valves. It is intended for plumbers working on residential drain and vent systems where a neat, secure pipe anchor point is required at the wall framing stage.
Designed as an OEM-style replacement and new-installation component for 2-inch DWV pipe rough-in assemblies in residential and light commercial plumbing systems.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and ensure the DWV system is depressurized and clear before beginning rough-in work. Secure the box to wall framing according to manufacturer guidelines before pipe insertion. This is a box-only product; verify that any companion vent valve or fitting is sourced and installed separately.
