Sioux Chief 870-B Bar-9 Behind-the-Wall Mounting Bracket

Sioux Chief 870-B Bar-9 Behind-the-Wall Mounting Bracket

The Sioux Chief 870-B Bar-9 is a behind-the-wall mounting bracket engineered for rough-in plumbing work, giving plumbing contractors a dependable anchor point before the wall gets closed in. As part of Sioux Chief's rough-in hardware lineup, the 870-B is designed to be installed between studs ahead of drywall, supplying the backing needed for a clean, professional installation. Manufactured in the United States, this bracket is packaged 100 pieces per carton, a quantity that suits production plumbers, remodelers, and distributors who need to keep behind-the-wall hardware in stock without frequent reorders. Because it is a rough-in component, the 870-B is meant to be installed by a licensed plumber or contractor during the framing stage, before drywall and finish work begin, so the mounting point is set correctly the first time.
