Appleton SPLG-3000-1 Support Plug 3 Inch

Product Description

The APPLETON SPLG-3000-1 is a 3-inch support plug designed for use in conduit and raceway systems. Support plugs are installed at conduit endpoints and junction points to provide mechanical support for conductors and prevent wire bundle sag in vertical runs. This fitting is a standard component in commercial and industrial electrical installations where code-compliant conductor support is required. Licensed electricians and electrical contractors install this type of fitting during conduit rough-in and wire-pulling operations.

The SPLG-3000-1 is suited for 3-inch conduit installations in commercial and industrial electrical systems. It is typically used in vertical conduit runs where conductor weight requires positive mechanical support at intervals defined by the National Electrical Code. Applications include service entrance conduit, large feeder runs, and vertical riser assemblies where conductor management is critical to safe and compliant installation.

Key Features

• 3-inch conduit size for large-diameter raceway applications
• Provides mechanical conductor support in vertical conduit runs
• Designed for use in commercial and industrial electrical systems
• Supports NEC-compliant conductor support intervals in vertical risers

Compatibility

Designed as an OEM-style fitting for use with 3-inch conduit and raceway systems in commercial and industrial electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for conductor support in vertical conduit runs. De-energize all circuits and verify the absence of voltage before working in any conduit or enclosure. Ensure the support plug is fully seated and secured within the conduit end before pulling conductors. Consult local electrical codes for required support spacing intervals on vertical runs.
