Sioux Chief 523-2420 Universal Pipe & Tube Clamp for 1/4" - 1" CTS Tube and Sch. 40 Pipe

Sioux Chief 523-2420 Universal Pipe & Tube Clamp for 1/4" - 1" CTS Tube and Sch. 40 Pipe

The Sioux Chief 523-2420 pipe and tube clamp is a rough-in plumbing support built to secure piping runs behind walls and under floors before the drywall goes up. It clamps 1/4" - 1" CTS tube as well as 1/8" - 1" Schedule 40 pipe, giving plumbers and contractors a single clamp style that covers both flexible tubing and rigid pipe sizes on the same job without swapping hardware or stocking two separate part numbers. Manufactured in the United States, it ships 50 pieces per carton so rough-in crews and service trucks can keep a practical stocking quantity on hand for repeat use across framing, remodel, and new-construction work.

Key Features

• Trade Size Coverage: Clamps 1/4" - 1" CTS tube, covering the common copper and plastic tubing sizes found in rough-in water distribution work.
• Pipe Compatibility: Also secures 1/8" - 1" Schedule 40 pipe, letting one clamp style serve both tube and rigid pipe installations on the same job.
• Rough-In Support: Holds piping firmly in place behind walls and under floors during new construction or remodel work, helping keep runs straight and reducing movement or noise once the wall is closed up.
• Dual-Range Design: A single clamp body spans two distinct size ranges, cutting down on the number of different clamp styles a crew has to carry on the truck or in the tool bag.
• Job-Site Packaging: Packed 50 EA per carton, sized for efficient restocking on rough-in jobs and service trucks rather than one-off retail packaging.
• Domestic Manufacturing: Produced in the United States as part of Sioux Chief's rough-in plumbing support line.

Why Sioux Chief?

Sioux Chief builds rough-in plumbing hardware that contractors rely on to keep piping secure and properly supported behind walls and floors before the finish work covers it up. The 523-2420 clamp's dual tube-and-pipe capacity means a plumber can carry fewer clamp styles to the job while still covering the 1/4" - 1" CTS tube and 1/8" - 1" Schedule 40 pipe sizes most commonly run in residential and light commercial rough-in. Combined with U.S. manufacturing and job-lot packaging of 50 EA per carton, it's a practical stocking item for plumbing crews handling mixed CTS tube and Schedule 40 pipe runs on the same project.
