Sioux Chief 525-34 Main Block Service Pipe Clamp, 1" CTS

The Sioux Chief 525-34 Main Block Service Pipe Clamp is a two-piece pipe support designed for rough-in water service line installations behind walls and under floors. It is compatible with copper, PEX, or CPVC tube, and securely holds 3/4", 1", and 1-1/4" CTS (copper tube size) tubing with a 1-1/2" offset from the mounting surface. This clamp is built for plumbers and contractors running main water service lines, appliance and fixture stub-outs, and water heater or water softener loops where a secure, code-grade mounting point is required on the pipe run.

Key Features

  • Trade Size: Securely holds 3/4", 1", and 1-1/4" CTS tube within a single clamp body, reducing the need for multiple part numbers on a jobsite.
  • Tube Compatibility: Works with copper, PEX, or CPVC tube, giving installers flexibility across water service line materials without changing hanger hardware.
  • 1-1/2" Offset: Provides a consistent 1-1/2" standoff from the wall or framing member, keeping the water line positioned for proper clearance and future access.
  • Two-Piece Design: The split, two-piece construction allows the clamp to be installed around tube that is already in place, making it practical for retrofit, remodel, and repair work where the pipe cannot be fed through a one-piece hanger.
  • Application-Ready: Purpose-built for water service lines, appliance and fixture stub-outs, and water heater/softener loop installations.

Technical Specifications

  • Country of Origin: United States

Why Sioux Chief?

Sioux Chief designs the 525-34 Main Block Service Pipe Clamp for the realities of a working jobsite - a single clamp body that spans 3/4", 1", and 1-1/4" CTS tube in copper, PEX, or CPVC means fewer part numbers to stock and carry. The two-piece design gives plumbers a practical way to add secure pipe support on existing runs during retrofit and repair work, without cutting or re-routing the line. Manufactured in the United States, this clamp is built to hold up to the demands of daily rough-in plumbing work on water service lines and appliance stub-outs.

Sioux Chief 525-34 – Frequently Asked Questions

1) Will the Sioux Chief 525-34 main block clamp hold 1 inch PEX, or is it copper only?
Copper, PEX, and CPVC all work in the 525-34. The clamp body is sized to CTS (copper tube size), so it takes 3/4 inch, 1 inch, and 1-1/4 inch CTS tube in any of those three materials without swapping hanger hardware.
2) Can I add a pipe clamp to a water line that is already installed, without cutting the pipe?
Yes, that is what the two-piece design on the Sioux Chief 525-34 is for. The split body closes around tube that is already in place, so you can add a support point during retrofit, remodel, or repair work without cutting or re-routing the run. A one-piece hanger would require feeding the pipe through it.
3) How far off the stud does the Sioux Chief 525-34 hold the water line?
It sets the tube 1-1/2 inches off the mounting surface. That fixed offset keeps the line standing clear of the framing member or wall for clearance and later access, and it keeps multiple clamps on the same run at a consistent depth.
4) Do I need a different Sioux Chief clamp for each pipe size on a rough-in?
Not across 3/4 inch through 1-1/4 inch CTS. The single 525-34 body covers all three sizes, so one part number handles the common water service and stub-out sizes on a job instead of three. Anything above 1-1/4 inch CTS needs a different support.
5) What jobs is the Sioux Chief 525-34 main block clamp actually used for?
Water service line mounting behind walls and under floors, appliance and fixture stub-out support, and water heater or water softener loop installation. Property maintenance crews also use it to add a secure mounting point on an existing line during repair work, since the two-piece body goes on without disturbing the pipe.
