4. Installation Instructions

This extension ring is designed to be installed between an existing 4-inch round weatherproof electrical box and a cover or fixture. Ensure all power to the circuit is turned off at the main breaker before beginning installation.

1. Safety First: Turn off power at the circuit breaker or fuse box before starting any electrical work. Verify power is off using a voltage tester.
2. Prepare the Existing Box: If a cover or fixture is currently installed, carefully remove it from the existing weatherproof box. Disconnect any wiring as necessary.
3. Position the Gasket: Place the provided gasket onto the back of the extension ring, ensuring it aligns with the mounting holes. This gasket helps maintain the weatherproof seal.
4. Mount the Extension Ring: Align the extension ring with the existing weatherproof box. Secure the extension ring to the box using the provided hardware. Ensure a snug fit to maintain weather resistance.
5. Wire Connections: Route any necessary wiring through the extension ring. Utilize the additional space provided by the extension ring for wire management and connections.
6. Install Cover/Fixture: Attach the original weatherproof cover or electrical fixture to the front of the extension ring using appropriate hardware. Ensure all connections are secure and the cover/fixture is properly sealed.
7. Seal Unused Openings: Insert the provided closure plugs into any unused 1/2-inch knockout holes on the extension ring to maintain its weatherproof integrity.
8. Restore Power: Once installation is complete and all connections are secure and sealed, restore power to the circuit at the main breaker.

5. Maintenance

The Sigma 14236 Weatherproof Extension Ring requires minimal maintenance. Periodically inspect the installation for any signs of wear, damage, or compromised seals, especially in outdoor or damp environments.

• Visual Inspection: Annually check the extension ring and surrounding components for cracks, corrosion, or loose connections.
• Seal Integrity: Ensure the gasket and closure plugs remain intact and provide a tight seal against moisture. Replace if damaged.
• Cleaning: If necessary, clean the exterior with a damp cloth. Avoid abrasive cleaners or solvents that could damage the powder-coated finish.

6. Troubleshooting

Most issues related to the extension ring are typically associated with improper installation or damage. Always ensure power is off before inspecting electrical components.

• Moisture Inside Box:
  • Check if the gasket is properly seated and undamaged.
  • Ensure all unused knockouts are sealed with closure plugs.
  • Verify that the cover or fixture attached to the extension ring is also properly sealed.
• Loose Connection/Ring:
  • Tighten all mounting screws securing the extension ring to the electrical box.
  • Ensure the cover/fixture is securely attached to the extension ring.
