Hammond CWJO4 Wireway Joiner Extra Coupling

Product Description

The HAMMOND CWJO4 is a wireway joiner and extra coupling designed to connect wireway sections end-to-end in electrical raceway installations. It maintains a continuous, secure enclosure for wire bundles and cable runs, keeping conductors organized and protected between joined sections. Licensed electricians and electrical contractors install this hardware during panel feed runs, industrial machine wiring, and commercial building distribution layouts where wireway sections must be extended or joined. At 5 pounds, this fitting is sized for straightforward field installation without heavy lifting equipment.

This joiner coupling is suited for use in commercial and industrial electrical installations where metallic wireway systems are specified. It applies wherever runs must be extended across longer distances or joined at transitions, including manufacturing floors, mechanical rooms, and electrical service corridors. Install teams reach for this part when laying out ladder-style or trough-style wireway systems that require additional coupling hardware beyond what ships with standard wireway sections.

Key Features

• Joins wireway sections end-to-end for continuous cable management runs
• Functions as an extra coupling where standard fittings are insufficient for the run length
• Compact hardware suitable for commercial and industrial raceway systems
• Consistent fit with HAMMOND wireway system components

Compatibility

Designed as an OEM-style joiner coupling for use with compatible metallic wireway raceway systems requiring end-to-end section connections.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for wireway systems. De-energize all circuits within the wireway before opening or modifying the raceway. Standard hand tools including screwdrivers and a torque driver are typically sufficient for securing coupling hardware. Verify that all conductors are properly rated for the completed raceway fill before closing the wireway covers.
