Sioux Chief 550-12 Touch Down Pipe Clamp, CTS/Sch. 40, Bulk 100-Pack

The Sioux Chief 550-12 Touch Down Clamp is a rough-in pipe clamp built for plumbers and mechanical contractors who need a fast, reliable way to secure copper, PEX, or CPVC lines to a mounting surface. Sized for 1/4" - 1" CTS and 1/8" - 1" Sch. 40 pipe, this clamp provides a 1/4" stand-off from the mounting surface and ships in a bulk box of 100 units for crews running multiple rough-in jobs. The locking mechanism allows for variable tension, so the clamp can be set tight for a rigid hold or loosened slightly to allow for pipe expansion and contraction behind the wall or under the floor.

Key Features

  • Trade Size: Fits 1/4" - 1" CTS and 1/8" - 1" Sch. 40 pipe, covering the most common rough-in supply and DWV line sizes on a single clamp body.
  • Pipe Compatibility: Compatible with copper, PEX, or CPVC tubing, making it a versatile stocking item for mixed-material rough-in work.
  • Mounting Stand-Off: Provides a 1/4" stand-off from the mounting surface, keeping pipe off framing and reducing contact-related wear.
  • Variable Tension Locking Mechanism: Allows the installer to clamp the pipe tightly or leave slack to accommodate thermal expansion and contraction over time.
  • Plenum-Rated Construction: The plenum-rated model meets ASTM E84 25/50 Flame/Smoke Spread and UL-94 V0 flame ratings, supporting use in plenum and air-handling spaces where flame/smoke spread performance is required.
  • Patented Design: Manufactured under Patent # 6,126,122.
  • Bulk Packaging: Packaged 100 per box for contractors and distributors stocking high volumes of rough-in pipe clamps.

Sioux Chief 550-12 – Frequently Asked Questions

1) What pipe sizes does the Sioux Chief 550-12 Touch Down clamp fit?
One clamp body covers 1/4 inch through 1 inch CTS tubing and 1/8 inch through 1 inch Sch. 40 pipe. That spans most rough-in supply runs and the smaller DWV lines, so a crew can stock a single clamp instead of a size-by-size assortment.
2) Can I use the 550-12 clamp on PEX, or is it copper only?
Copper, PEX, and CPVC all work in the 550-12. It is a locking clamp rather than a material-specific strap, which is why mixed-material rough-ins can run off one box.
3) Will this clamp hold the pipe tight, or can it allow for expansion and contraction?
Both, and that is the point of the variable tension lock. Set it tight for a rigid hold, or back it off slightly so a hot water line can move as it heats and cools instead of binding and ticking behind the wall.
4) Does the 550-12 hold the pipe away from the framing?
Yes, it mounts the line with a 1/4 inch stand-off from the surface. That gap keeps copper or CPVC off the stud face, which cuts abrasion where the pipe moves and leaves room for the tubing to shift without rubbing wood.
5) How many clamps come in a box of Sioux Chief 550-12?
The 550-12 is bulk packed 100 per box. It is the stocking configuration for contractors running repeat rough-ins and for distributors who move pipe clamps by the case rather than the handful.
6) Do I need a separate clamp for 1/2 inch copper and 3/4 inch PEX on the same rough-in?
No. The same 550-12 body takes both, since it covers 1/4 inch to 1 inch CTS and works on copper, PEX, and CPVC. One part number on the truck handles a mixed supply rough-in instead of three.
