Southwire 133 Rigid Emt 2-hole Steel Strap 4 Inches

Product Description

The SOUTHWIRE 133 is a steel 2-hole strap designed for securing rigid metal conduit and EMT to structural surfaces such as framing members, joists, and concrete. This strap provides a firm, dual-fastener hold that resists lateral movement and vibration, making it a standard hardware item in commercial and residential electrical rough-in work. The strap is sized for 4-inch conduit and is constructed from galvanized steel at the larger sizes, giving it solid corrosion resistance for both indoor and covered outdoor installations. Electricians use this fitting wherever code requires conduit to be supported at consistent intervals.

This strap is used in standard conduit-support applications for rigid and EMT conduit runs in new construction, renovation, and industrial settings. It is appropriate for use in both residential and light commercial electrical work where conduit must be anchored to wood, metal, or masonry substrates. The two-hole design distributes load across two fastener points, which is required by NEC guidelines for rigid conduit support in many installation scenarios.

Key Features

• Two-hole design provides dual-fastener support for rigid and EMT conduit
• Galvanized steel construction for 4-inch size offers corrosion resistance
• Sized for 4-inch conduit for a secure, close-fitting hold
• Manufactured in the United States
• One-year limited warranty

Compatibility

Designed as an OEM-style replacement and standard-supply strap for 4-inch rigid metal conduit and EMT conduit support applications in residential and commercial electrical installations.

Installation Notes

Installation is performed by licensed electricians during conduit rough-in. Power down circuits in the work area before beginning conduit support work. Fasten both holes of the strap to the substrate using appropriate fasteners for the material type, whether wood screws, sheet metal screws, or masonry anchors. Follow NEC Article 344 and Article 358 for rigid and EMT conduit support spacing requirements.
