Step-by-Step Installation Guide 

 

1. Planning and Measurement 

Start by assessing the area where the dado trunking will be installed. Measure the length required for each section, ensuring precise dimensions. Mark the wall with a pencil to indicate the positioning of the trunking. 
 

2. Cutting Dado Trunking Sections 

Using a hacksaw, carefully cut the dado trunking sections according to your measurements. Ensure smooth, even cuts for a professional finish. 
 

3. Positioning and Alignment 

Hold the cut dado trunking section against the wall to check the alignment and positioning. Use a level to ensure that the trunking is straight and even. 
 

4. Marking and Drilling 

Mark the positions for screw holes along the base of the trunking. Use a drill to create holes for the screws and wall plugs, ensuring a secure attachment to the wall. 
 

5. Mounting the Trunking 

Place the dado trunking against the wall, aligning it with the drilled holes. Insert wall plugs into the holes and secure the trunking using screws. 
 

6. Cable Management 

Arrange and organise the cables within the trunking, using cable management accessories to secure them. This step is crucial for maintaining a tidy and efficient wiring system. 
 

7. Additional Sections (If Needed) 

Repeat the cutting, positioning, and mounting steps for additional dado trunking sections. Ensure a seamless connection between sections for a professional appearance. 
 

8. Final Checks 

Double-check the alignment and stability of the installed dado trunking. Use a level to confirm that all sections are straight and properly mounted. 

 

Frequently Asked Questions (FAQs) 

1. How do I choose the right size of dado trunking for my project?

2. Can dado trunking be used in outdoor installations? 

Dado trunking is primarily designed for indoor installations. For outdoor cable management, consider using weatherproof conduit systems.
 

3. What safety precautions should I take during installation? 

Wear safety gloves and glasses to protect yourself from potential hazards. Additionally, ensure that the electrical power is turned off before working with cables. 
 

4. Is it possible to paint or decorate dado trunking? 

Yes, dado trunking can be painted or decorated to match the surrounding environment. Use paint suitable for plastic surfaces and follow the manufacturer's guidelines. 
 

5. Can I install dado trunking on uneven walls? 

It's recommended to install dado trunking on flat and even surfaces for stability and a professional appearance. If the wall is uneven, consider using spacers to achieve proper alignment. 
 

6. Are there alternatives to screws for mounting dado trunking? 

Yes, adhesive tape designed for cable management can sometimes mount dado trunking. However, screws and wall plugs provide a more secure and reliable attachment.
