Eaton B-line Fig. 4L 3PLN Inline Sway Brace Attachment Size 3

Product Description

The EATON B-LINE FIG. 4L 3PLN is a size 3 inline sway brace attachment with a plain finish, designed for seismic bracing applications in mechanical and electrical systems. Inline sway brace attachments connect bracing rods or strut assemblies to pipe or conduit runs, limiting lateral and longitudinal movement during seismic events. This unit ships as a single piece and is installed by licensed mechanical, plumbing, or electrical contractors working on seismic restraint systems in commercial and industrial construction.

This attachment is suited for inline bracing configurations where a rigid connection point is required along the run of a pipe, conduit, or duct system. Size 3 designates the fitting class, which determines the load range and compatible hardware for the assembly. The plain finish is appropriate for interior dry installations where corrosion protection is not a primary requirement. It is commonly used in commercial buildings, institutional facilities, and industrial plants subject to seismic design requirements.

Key Features

• Inline configuration provides a mid-run attachment point for sway brace assemblies
• Size 3 fitting class for compatibility with corresponding bracing hardware
• Plain finish suited for interior dry-location installations
• Single-unit selling configuration for precise quantity ordering
• Designed for seismic restraint systems in mechanical and electrical installations

Compatibility

Designed as an OEM-style inline sway brace attachment for use within seismic bracing systems requiring size 3 inline attachment hardware with a plain finish.

Installation Notes

Installation should be performed by a licensed contractor familiar with seismic bracing requirements and applicable codes, including NFPA 13 for fire protection or SMACNA guidelines for duct and pipe bracing. De-energize or shut off the associated system before attaching or adjusting any bracing hardware. Verify that the attachment size and load rating are appropriate for the pipe or conduit size and the calculated seismic loads before installation. Follow the project engineer or authority having jurisdiction specifications for brace spacing and angle.
