Southwire 343 Malleable Right Angle Pipe Clamp 1 Inch

Product Description

The SOUTHWIRE 343 is a 1-inch malleable right angle pipe clamp designed to secure conduit and pipe runs at 90-degree angles to structural surfaces. Malleable iron construction provides the durability and thread integrity required for permanent electrical and mechanical installations. This clamp is a standard hardware item installed by licensed electricians and pipefitters in both new construction and retrofit applications. It holds pipe firmly against walls, ceilings, or structural members while maintaining precise right-angle alignment, reducing movement and vibration in conduit systems.

The 343 is suited for 1-inch pipe or conduit in commercial and residential electrical installations, as well as light mechanical piping runs. Typical install scenarios include securing EMT, rigid conduit, or pipe to concrete, steel, or wood framing. This clamp is a recognized equivalent to Madison 343RA and Topaz 1553HDG, making it a direct cross-reference option when sourcing for service or new work.

Key Features

• Malleable iron construction for strength and resistance to cracking under load
• Right angle geometry secures pipe flush against mounting surfaces at 90 degrees
• 1-inch pipe size fits standard 1-inch conduit and pipe OD
• Cross-references Madison 343RA and Topaz 1553HDG for direct substitution
• One year limited warranty from manufacturer

Compatibility

Listed as a direct equivalent to Madison 343RA and Topaz 1553HDG. Designed for use with 1-inch nominal pipe or conduit in standard electrical and mechanical piping installations.

Installation Notes

Installation is typically performed by a licensed electrician or pipefitter. Secure the mounting surface before attaching the clamp, and ensure fasteners are appropriate for the substrate material. Follow NEC requirements for conduit support spacing when using this clamp in electrical raceway systems. Do not overtighten fasteners on malleable iron fittings, as excessive force can crack the body.
