Sioux Chief 69654 One-Hole ABS Access Box for DWV Pipe

Sioux Chief 69654 One-Hole ABS Access Box for DWV Pipe

The Sioux Chief 69654 One-Hole Access Box is a tough ABS enclosure designed for rough-in installations where a drain-waste-vent (DWV) pipe needs to pass through a wall cavity with a secure, concealed mounting point. Built for plumbers and contractors working behind the wall, this access box installs directly to or between wall studs, giving the DWV pipe a stable, code-friendly anchor point before the wall finish goes up. This access box is available in 1-1/2" and 2" sizes to match the DWV pipe penetration on the job, while the one-hole configuration keeps the box simple and purpose-built for a single pipe penetration at either size, making it a straightforward rough-in component for new construction or renovation plumbing work. Supplied in a carton of 10 EA, it's sized for jobs that call for multiple access points across a run of framing, so a plumbing crew can stock up for a full floor or building without re-ordering mid-job, selecting whichever of the 1-1/2" or 2" sizes matches the pipe run at hand. As with any ABS plumbing product sold in California, this item carries a Prop 65 warning, which is standard disclosure language rather than a statement about the product's performance or suitability.
