Abb G978A Galvanized Channel Joiner Strut Fitting

Product Description

The ABB G978A is a galvanized channel joiner used to connect and extend sections of strut channel in electrical, mechanical, and plumbing support systems. This fitting slips over adjacent channel ends to form a continuous, rigid run without interruption. The galvanized finish provides corrosion resistance for use in both indoor and exposed environments. Electricians, plumbers, and mechanical contractors install this type of fitting when building out support frameworks for conduit, pipe, cable tray, and equipment. At 103.75 pounds per package, this is a bulk-quantity item suited for larger framing projects.

Channel joiners like the G978A are used in commercial and industrial installations where strut channel must span long distances or where sections must be field-joined after cutting. Typical applications include equipment support racks, pipe hangers, conduit ladder systems, and overhead mechanical supports in facilities requiring extended channel runs. This joiner is appropriate for both new construction and retrofit work.

Key Features

• Galvanized finish resists corrosion in indoor and semi-exposed environments
• Designed to join and extend strut channel runs end-to-end
• Bulk package suitable for larger-scale framing and support projects
• Compatible with standard strut channel framing systems used across electrical and mechanical trades

Compatibility

Designed as an OEM-style replacement and standard fitment joiner for galvanized strut channel support systems used in electrical, plumbing, and mechanical installations.

Installation Notes

Installation is typically performed by licensed electricians or mechanical contractors working under NEC or IPC guidelines where applicable. De-energize any nearby electrical systems before working on support structures in live panels or energized areas. Use appropriate hardware torqued per the support system manufacturer recommendations and inspect channel ends for burrs or deformation before fitting the joiner. Follow local code requirements for support spacing and load ratings.
