Sioux Chief 525--24 Strong Arm Pipe Support Bracket with LockBlocks

Sioux Chief 525--24 Strong Arm Pipe Support Bracket with LockBlocks

The Sioux Chief 525--24 Strong Arm is a rough-in pipe support bracket built to rigidly secure CTS stub outs inside the wall before drywall goes up. This family is available with a selectable LockBlock configuration, offered as either One LockBlock or Two LockBlocks, so installers can match the clamping setup to the demands of the stub-out application. Each LockBlock grips both the tubing and the mounting bracket simultaneously when the screws are tightened, locking the stub out in place and preventing movement during rough-in, drywall installation, and final fixture hookup. Every configuration in this family is rated to secure any 1/2" - 1" CTS stub out, making it a versatile choice for supply lines run to washing machine boxes, ice maker outlets, hose bibbs, and other fixture stub outs that need a solid, immovable anchor point. The bracket design is covered under Patent #8,061,390, reflecting the engineered LockBlock clamping mechanism that sets this product apart from simple strap-style hangers.

Key Features

• Trade Size: Rigidly secures any 1/2" - 1" CTS stub out and prevents all movement once installed, across every LockBlock configuration in this family.
• Selectable LockBlock Configuration: Choose One LockBlock or Two LockBlocks depending on how much clamping force the stub-out application requires—each LockBlock grips both the tube and the bracket itself when the mounting screws are tightened, creating a solid mechanical lock rather than a simple friction fit.
• Dual Mounting Options: L-bend brackets are designed to mount inside the stud cavity, while twisted brackets mount to the face of the stud, giving installers flexibility based on framing layout and stub-out location.
• Patented Design: Covered under Patent #8,061,390 for the engineered bracket and LockBlock system shared across the entire family.
• Behind-the-Wall Application: Built for rough-in use, anchoring CTS supply stub outs before wall finishing so fixtures land exactly where planned.

Why Sioux Chief?

Sioux Chief engineers rough-in plumbing hardware that plumbers rely on to get stub outs right the first time, since callbacks for a loose or misaligned supply line are costly once walls are closed. The patented LockBlock clamping design on the Strong Arm bracket gives installers a mechanical lock on both the tube and the bracket itself, not just a friction strap, so the stub out stays exactly where it was set during framing and rough-in inspection. With a selectable One or Two LockBlock configuration plus flexible L-bend and twisted bracket mounting options, this Sioux Chief Strong Arm bracket family fits a range of stud cavity and face-mount framing conditions on the job site. Every unit ships ready to anchor supply stub outs for washing machine boxes, ice makers, hose bibbs, and other fixture connections, giving contractors a dependable, code-ready rough-in solution backed by a patented design.
