Sioux Chief C634 Plastic 2-hole Pipe Clamp 3/4 Inch

Product Description

The SIOUX CHIEF C634 is a two-hole plastic pipe clamp designed to secure 3/4-inch CTS (copper tube size) pipe runs in residential and light commercial plumbing installations. Molded from polypropylene, this clamp provides a lightweight, corrosion-resistant hold rated for up to 25 pounds of load capacity. At 2.617 inches in length and 1.275 inches in height, it fits snugly against framing or structural surfaces. The ivory-colored body is easy to identify on the job site, and the two mounting holes accept standard fasteners for quick, secure attachment. Plumbers and pipefitters use this clamp when strapping water supply lines, CTS distribution runs, or similar tubing to wood or metal framing.

This clamp is suited for 3/4-inch CTS pipe support in residential water supply systems, light commercial plumbing, and retrofit applications where corrosion resistance matters. The two-hole design distributes load evenly and keeps the pipe centered and stationary, reducing vibration and movement over the life of the installation. It is a direct-install component that requires no special tools beyond a standard drill and appropriate fasteners for the substrate.

Installation Notes

Installation is typically performed by a licensed plumber or qualified pipefitter. Shut off the water supply and depressurize the line before repositioning or replacing pipe supports.
