“dado trunking is a type of cable management system used to conceal and organize electrical wires and cables. It is typically installed at a low level on walls and is commonly used in commercial and industrial buildings, especially in large projects where there is a significant need for cable management.

The sizes of dado trunking can vary based on the manufacturer and the specific requirements of the project. Common sizes of dado trunking include:

Small Dado Trunking: Usually around 50mm to 75mm in height and suitable for smaller cable management needs in less complex installations.

Medium Dado Trunking: Often around 75mm to 100mm in height, providing more capacity for cables and wires and catering to medium-sized installations.

Large Dado Trunking: This type can be around 100mm to 150mm or more in height and is suitable for larger projects with higher cable density.

For large projects, a wide range of fittings and accessories are available to accommodate various cable management requirements and ensure a neat and efficient installation. Some common fittings used in large dado trunking installations include:

External and Internal Angles: Used to change the direction of the trunking around corners and bends.

Flat and Tee Junctions: These fittings allow the trunking to branch off or merge with other sections.

End Caps: Used to seal off the open ends of the trunking to provide a clean finish.

Couplers: Used to join two lengths of trunking together when longer runs are required.

Dividers: To create separate compartments within the trunking for better cable organization and segregation.

Cable Retainers and Fixings: Various accessories to secure and manage cables within the trunking.

Mounting Brackets: To fix the trunking securely to walls or other surfaces.

Power and Data Outlets: Integrated sockets and data points can be installed within the trunking for easy access to power and network connections.

It’s important to note that advancements in cable management technology and the availability of different products may have changed since my last update. For large projects, it’s recommended to consult with cable management specialists or manufacturers to get the most up-to-date information and appropriate solutions based on specific project requirements.”
