Subtle art of fishing HDMI cable through wall


Setting up the perfect home theater system includes installing various components and hiding unsightly wires. Among these components, HDMI cables are essential for connecting devices like gaming consoles, Blu-ray players, or streaming devices to your TV or projector. To achieve a clean and clutter-free look, fishing HDMI cables through walls is the way to go. In this article, we'll explore the step-by-step process of accomplishing this task efficiently and without any hassle.

Understanding the HDMI Cable

Before we dive into the fishing process, it's important to understand the HDMI cable itself. HDMI stands for High-Definition Multimedia Interface, and these cables transmit both audio and video signals with exceptional quality. They are equipped with a compact connector on each end, which can be delicate. It is essential to handle them gently to ensure their integrity throughout the fishing process.

1. Preparing for the task

To successfully fish an HDMI cable through a wall, you'll need some tools and materials. Before you start, gather the following items:

- HDMI cable(s) of appropriate length.

- Fish tape or wire coat hanger.

- Electrical tape.

- A flashlight or headlamp.

- A drill with a long, flexible bit.

- A stud finder.

- A power drill with paddle bit.

- Drywall saw.

- Wall plates.

- Screwdriver.

2. Mapping the route

To avoid drilling into any electrical wires or vertical studs, it's crucial to plan the route carefully. Use a stud finder to detect any vertical beams or obstructions within the wall. Make sure to choose a route that does not interfere with any electrical work. It's best to stay away from electrical wires altogether, even if they are shielded. Once you have identified a clear path, note any turns or corners the cable would need to make.

3. Preparing the walls

To create entry and exit points for the cable, you need to make holes in the walls. Use a power drill with a paddle bit to make an appropriate-sized hole, typically around 1.5 inches, at the starting and endpoint of your cable route. Be cautious while drilling to avoid excessive force or misalignments that could damage the wall. Once the holes are made, smooth out any rough edges using sandpaper for a clean finish.

4. Fishing the cable

Attach the HDMI cable to a fish tape or a straightened wire coat hanger using electrical tape. The fish tape should be long enough to reach from one hole to the other without much difficulty. Slowly and carefully insert the fish tape or coat hanger into the starting hole you drilled, ensuring it follows the planned route. Use a flashlight or headlamp to illuminate the path to help guide you through any turns or narrow sections. When you reach the endpoint, firmly hold the cable and pull it through until the connector is visible. Avoid pulling excessively, as this could damage the cable.

5. Installing wall plates

To provide a finished and professional appearance, install wall plates at both the entry and exit points. A wall plate consists of a faceplate and an insert. Choose a wall plate compatible with HDMI connectors and attach the faceplate to the wall using a screwdriver. Then, insert the HDMI connectors into the appropriate ports and screw the insert into the faceplate. Ensure the connections are tight and secure to maintain optimal signal quality.

6. Concealing the cable

If you wish to completely hide the visible portion of the HDMI cable, consider using cable raceways or in-wall solutions. Cable raceways are adhesive strips that adhere to the wall, providing a small channel along which you can run your HDMI cable. In-wall solutions involve cutting small horizontal channels in the drywall where the cable can be run before patching and repainting the wall. Both methods help achieve a seamless and clutter-free appearance.


Fishing an HDMI cable through a wall might seem daunting at first, but with careful planning and the right tools, it can be a straightforward process. Remember to handle the delicate HDMI cable with care, choose an appropriate route, and make accurate holes to ensure a smooth fishing experience. By following the steps outlined in this article, you can effortlessly achieve a professional installation and enjoy a clean and organized home theater setup.
