Understanding Bell Mouth vs. Spigot

People often use terms like “bell mouth” and “spigot” (or pit spigot bush) interchangeably when discussing this conduit accessory. However, understanding the differences between these two can help you choose the right product for your needs.

Spigot (Pit Spigot Bush)

  • Design and Use: A spigot is a molded product specifically designed for plastic pits.
  • Key Features:
    • Rounded edges to prevent cable damage.
    • Connects conduits securely to the pit.
  • Ideal Applications: Use spigots in plastic pits to securely attach the conduit without damaging the cables.


Bell Mouth

  • Design and Use: The bell mouth is a bell-shaped extension typically used in concrete pits.
  • Key Features:
    • Can be made to specific lengths to fit various concrete pit walls.
    • Offers the same protective function as a spigot bush, but in a different context.
    • Customizable to meet specific needs and available in standard sizes.
  • Ideal Applications: Suitable for concrete pits where custom lengths and additional protection are required.


Key Features and Benefits of Electrical PVC Conduit Bell Mouth

How Installers Use Bell Mouths in Concrete Pits

Installers use bell mouths in concrete pits for safe and efficient cable management. Installers place the flared, bell-shaped opening at conduit entry and exit points, allowing cables to transition smoothly and reducing friction and abrasion. Customizable to specific lengths, bell mouths ensure a perfect fit within concrete pit walls, providing added support and stability. This customization is crucial for complex installations requiring precise alignment. The robust construction of bell mouths withstands demanding industrial and commercial environments, extending the lifespan of the communication system. Ultimately, using bell mouths in concrete pits is essential for enhancing the durability and reliability of cable installations.


Differentiating Austel and Telstra/NBN Sizes

In communication applications, it is crucial to understand the specific size distinctions for proper installation:

  • 20mm and 50mm Sizes: The Austel standard measures these sizes from the outside diameter, while the Telstra/NBN standard, also used in rail projects, measures from the inside diameter. This difference is vital for ensuring compatibility with service requirements.
  • 100mm Size: This size is standardized and identical across both Austel and Telstra/NBN specifications, simplifying the installation process for this dimension.

Understanding these distinctions is essential to ensure your installations meet the required specifications and perform optimally. Always verify the required standard before proceeding with the installation to avoid compatibility issues.


Applications of Communication Conduit Bell Mouth

  • Residential Wiring: Protect your home’s wiring system with our durable bell mouth.
