Description
Wall Box Steel Extension 4×2″ is a steel extension accessory designed to increase the depth or capacity of an existing 4×2 (4 inches by 2 inches) electrical wall box. These extensions are useful in situations where additional space is required within a box for more wiring or devices. Here’s an overview of its features and uses:
Key Features:
- Material: Made from steel, offering durability, fire resistance, and grounding capabilities.
- Dimensions: The 4×2 measurement corresponds to the width and height of a standard 4×2 electrical box, so the extension will align perfectly with these boxes.
- Depth Extension: Typically adds an extra 1-1/2 inches or more in depth, allowing for increased capacity within the existing box.
- Knockouts: Often includes knockouts (removable sections) to facilitate conduit or cable entry as needed.
- Compatibility: Designed to be used with standard 4×2 metal or PVC boxes, providing a seamless extension.
Uses:
- Increased Wiring Space: Provides additional space for wiring, connectors, or splices in applications where the original box is too small.
- Retrofitting and Upgrades: Useful for retrofitting applications, particularly when upgrading or modifying circuits with additional wires or devices.
- Extra Device Mounting: Offers room to install more devices like switches or outlets without the need to replace the original box entirely.
Code and Safety:
- Compliance with NEC: The National Electrical Code (NEC) mandates that boxes must have sufficient volume to avoid overcrowding, making extensions a practical solution for ensuring code compliance.
- Grounding Requirements: As part of the electrical system, metal extension boxes must be grounded properly to maintain electrical safety and fault protection.
Benefits of Steel:
- Durability: Steel extensions are robust and suitable for areas where extra protection is needed, like garages or industrial settings.
- Fire Resistance: Steel extensions can contain sparks and resist high temperatures better than non-metallic options, offering added fire protection.
- Easy Installation: The extension can be quickly mounted to an existing box, providing immediate extra space without a major installation overhaul.
The Wall Box Steel Extension 4×2 is a practical, code-compliant solution for expanding the capacity of a standard 4×2 electrical box. Its durability, fire resistance, and grounding capabilities make it a solid choice for both residential and commercial electrical upgrades or retrofits.
