Southwire 346-P Malleable Parallel Pipe Clamp

Product Description

The SOUTHWIRE 346-P is a malleable parallel pipe clamp designed for securing and supporting parallel runs of pipe in mechanical and electrical trade applications. This fitting-style clamp uses malleable iron construction for durability in demanding installation environments where vibration resistance and structural integrity are required. Licensed trades including plumbers, pipefitters, and electrical contractors rely on this type of clamp when routing multiple pipe runs in close parallel alignment. It provides a stable, rigid connection point that reduces movement and simplifies neat, code-compliant installations.

The 346-P suits residential and commercial mechanical applications where parallel pipe support is needed along walls, ceilings, or structural members. It is a common component in plumbing rough-in, conduit support, and HVAC piping installations. The clamp is sized and configured for use in situations where two pipe runs must be held in a fixed parallel orientation without drift or separation over time.

Key Features

• Malleable iron construction provides strength and resistance to cracking under load
• Parallel clamp design secures two pipe runs simultaneously in fixed alignment
• Suitable for use in mechanical, plumbing, and electrical support applications
• Compact form factor fits standard framing and structural support intervals
• One-year limited warranty backed by SOUTHWIRE

Compatibility

Designed as an OEM-style parallel pipe clamp for use in residential and light commercial piping support applications where malleable iron clamps are specified.

Installation Notes

Installation of pipe clamps should be performed by a licensed plumber, pipefitter, or qualified mechanical contractor in accordance with applicable IPC and IFGC requirements. Shut off all fluid flow and depressurize the piping system before beginning any support or clamp work. Use appropriate fasteners rated for the mounting substrate and verify clamp positioning meets code-required support spacing for the pipe material and diameter being used. Do not overtighten fasteners, as this can distort the clamp body and compromise the pipe surface.
