Hiding the wires for a wall-mounted TV can be achieved through two primary methods: using a surface-mounted cord channel for a simple, non-invasive solution or installing in-wall cable plates for a completely clean look. The safest approach requires using in-wall rated, UL-listed cables to meet National Fire Protection Association (NFPA) codes and prevent fire hazards. This guide outlines both techniques, emphasizing critical safety precautions to ensure a professional and secure installation.
For renters or homeowners seeking a quick, reversible solution, a surface-mounted cord channel is the most straightforward option. This method involves adhering a plastic raceway directly to the wall surface to conceal the cables. A cord channel, also known as a wire raceway, is a plastic or PVC casing that bundles and hides cables running along a wall.
The process requires minimal tools: a tape measure, a level, a pencil, and a PVC cutter. First, measure the distance from the TV to the power outlet. Cut the channel to length, peel the adhesive backing, and press it firmly onto the wall. Use a level to ensure it is straight before inserting the cables and snapping the cover closed. The main advantage is the absence of drywall cutting, but the channel remains visible on the wall.
For a permanent, seamless appearance, running cables behind the drywall is the preferred method. This is ideal for homeowners who are comfortable with basic DIY projects involving drywall modification. However, this approach carries significant safety considerations that must be addressed first.
The most critical rule is to never run a standard power cord inside a wall. According to the National Electrical Code (NEC), standard power cords are not rated for in-wall use and can overheat, creating a serious fire hazard. You must use a power extension kit or in-wall power cable that is UL-rated for this specific purpose. UL, or Underwriters Laboratories, is an independent organization that certifies product safety. Always verify that all cables, including HDMI and audio cables, are rated for in-wall installation.
Executing an in-wall installation requires careful planning and the right tools: a stud finder, a utility knife or drywall saw, a screwdriver, and two low-voltage cable plates. These plates resemble light switch covers and provide a clean finish for the entry and exit points of the cables.
Locate Studs and Plan the Path: Use a stud finder to identify wall studs. The TV mount is already anchored to studs, so the ideal location for the top cable plate is in the empty drywall cavity between them. Mark the location for the top plate directly behind the TV and the bottom plate near the baseboard or outlet.
Cut Openings for Cable Plates: Most cable plates include a template. Tape the template to the wall and use a utility knife to carefully cut along the outline. Cut just deep enough to penetrate the drywall, then remove the cut-out section.
Fish the Cables: Feed the UL-rated cables through the top opening downward into the wall cavity. From the bottom opening, use a fish tape or a coat hanger to grab the cables and pull them through. This step, known as fishing wires, can be the most challenging part of the process.
Install the Plates and Re-mount the TV: Push the cables through the openings in the cable plates and screw the plates securely to the wall. Finally, reconnect all cables to the TV and power source before lifting the TV back onto its mount.
Compliance with local building codes is not optional; it is essential for safety. The primary concern is using the correct materials. Always purchase cables and power kits that are clearly marked "in-wall rated" or "CL2/CL3 rated." These certifications indicate the wiring has fire-resistant insulation suitable for running inside walls. Based on our experience assessment, consulting the manufacturer's specifications for both the TV and the cables is the best way to guarantee compliance. If you are unsure about any step, hiring a licensed low-voltage technician is a recommended precaution.
In summary, successfully hiding TV wires depends on choosing the right method for your skill level and goals. For a temporary, easy fix, a surface-mounted cord channel is the most practical choice. For a permanent, professional look, an in-wall installation with properly rated cables is mandatory for safety. The key takeaway is to prioritize the use of UL-listed, in-wall rated components to protect your home and meet electrical codes.
