Arlington Industries 3104 1-hole Metallic Strap 1.5 in

Product Description

The ARLINGTON INDUSTRIES 3104 is a single-hole metallic conduit strap sized for 1.5-inch conduit. This hardware accessory secures rigid metal conduit (RMC), intermediate metal conduit (IMC), or similar metallic raceway to structural surfaces such as walls, joists, and strut. It is sold individually and is a standard component in electrical rough-in work. Electricians reach for single-hole straps when a low-profile, code-compliant support point is needed along a conduit run.

The 3104 is suited for commercial and residential electrical installations wherever 1.5-inch metallic conduit requires periodic support per NEC spacing requirements. It is used in new construction and retrofit work alike, mounting directly to wood framing, concrete, masonry, or metal structure with a single fastener through the center hole.

Key Features

• Sized for 1.5-inch conduit outside diameter
• Single-hole mounting design for fast, single-fastener installation
• Metallic construction for grounding continuity along the conduit system
• Sold as individual unit (each)
• Compatible with standard electrical hardware accessory applications

Compatibility

Designed as an OEM-style support fitting for 1.5-inch rigid metal conduit or intermediate metal conduit runs in standard electrical installations.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC Article 344 or 342 spacing and support requirements. Power down the circuit before working near any energized conduit. Secure the strap with an appropriate fastener for the substrate — concrete anchors for masonry, wood screws for framing, or machine screws for metal structure. Do not over-tighten to the point of deforming the strap, as this can stress the conduit wall.
