Sioux Chief 559 Split Snap-On CTS Tube Clamp

The Sioux Chief 559 Split Snap-On CTS Tube Clamp is a rough-in pipe support built for jobs where copper, PEX, or CPVC tube needs to be secured behind a wall or under a floor. This split-design clamp line is available in 1-1/4", 1-1/2", and 2" CTS (copper tube size) sizing, so contractors can standardize on one clamp style across a mixed rough-in run instead of stocking multiple strap types. Each clamp snaps directly onto the tube for a fast, tool-light installation that eliminates fumbling with open-ended straps. Internal ribs inside the clamp body allow the tube to expand and contract with temperature changes, reducing the ticking and clicking noise that rigid, unlined supports can transmit through a structure. Because the 559 line is rated for use across copper, PEX, and CPVC, a single clamp style can be standardized across a mixed-material rough-in job, simplifying material stocking for plumbing contractors and MRO buyers alike. Plenum-rated versions of this clamp line meet ASTM E84 25/50 flame/smoke spread limits and the UL94 V-0 flame rating, which matters for installs run through air-handling spaces where combustibility of support hardware is a code consideration. Supplied in bulk packaging of 250 EA, the 559 line is sized for contractors and distributors stocking high-volume rough-in supports rather than one-off repair jobs.

Key Features

  • Trade Size Range: Available in 1-1/4", 1-1/2", and 2" CTS sizing, matching standard copper tube sizing used in rough-in water distribution and drain lines.
  • Split, Snap-On Design: The clamp body splits open and snaps closed around the tube, allowing installation without threading the clamp down the length of the pipe run.
  • Multi-Material Compatibility: Rated for use with copper, PEX, or CPVC tubing, so one clamp line covers multiple pipe materials on the same job.
  • Internal Ribbing: Internal ribs let the tube expand and contract within the clamp, reducing noise transmission compared to a rigid, unlined support.
  • Plenum-Rated Flame/Smoke Performance: Plenum-rated models meet ASTM E84 25/50 flame/smoke spread limits and the UL94 V-0 flame rating for use in air-handling spaces.
  • Bulk Case Packaging: Packaged 250 EA per case for contractors and distributors supplying volume rough-in work.

Why Sioux Chief?

Sioux Chief builds rough-in hardware around the realities of the jobsite, and the 559 line reflects that with a split, snap-on clamp body that installs quickly across 1-1/4", 1-1/2", and 2" CTS sizing, plus internal ribbing that keeps tube movement quiet over the life of the system. Compatibility across copper, PEX, and CPVC, along with a plenum-rated flame/smoke option, gives contractors and distributors a single, versatile support line for mixed-material rough-in work.

Sioux Chief 559-5 – Frequently Asked Questions

1) Will the Sioux Chief 559 snap-on clamp work on PEX and CPVC, or is it copper only?
The 559 split snap-on clamp is rated for copper, PEX, and CPVC tube, so one clamp style covers a mixed-material rough-in. Note that it is sized to CTS (copper tube size), so you order by the CTS trade size of the tube you are strapping, not by a separate PEX or CPVC sizing scheme.
2) What tube sizes does the Sioux Chief 559 tube clamp come in?
Three CTS sizes: 1-1/4 inch (559-5), 1-1/2 inch (559-6), and 2 inch (559-7). If your run is smaller than 1-1/4 inch CTS, this clamp line will not close around it and you need a smaller-size clamp.
3) Can I use these clamps on pipe runs through a return air plenum?
Plenum-rated versions of the 559 clamp line meet the ASTM E84 25/50 flame and smoke spread limits and the UL94 V-0 flame rating, which is what inspectors look for on support hardware inside air-handling spaces. Specify the plenum-rated version when the run is in a plenum; the standard version is for concealed wall and floor rough-in.
4) Do I have to thread this clamp onto the end of the pipe, or can it go on an installed run?
The 559 body is split, so it opens and snaps closed around tube that is already in place. No sliding it down the length of a run and no open-ended strap to wrestle with, which is the point of the design on retrofit and tight-bay work.
5) Will these clamps stop the ticking noise from hot water lines in the walls?
Internal ribs inside the clamp body let the tube expand and contract within the clamp instead of binding against a rigid support, which cuts the ticking and clicking that gets transmitted into framing. That is the main reason to use the 559 over a plain unlined strap on hot water distribution.
6) Can I standardize one clamp across copper, PEX, and CPVC on the same building?
Yes, and that is the practical argument for the 559. Because the line is rated across all three materials in 1-1/4, 1-1/2, and 2 inch CTS, a facility or a multi-family rough-in can carry one clamp style instead of separate strap types per pipe material. The clamps are made in the United States.
7) How are the Sioux Chief 559 clamps packaged, and is this practical for a small repair job?
They come in bulk cases of 250 each. That is a stocking quantity aimed at contractors and distributors running volume rough-in work, not a handful for a single repair.
