Conceal and Bury Cords

Let me start off by disclaiming this is just a way to run cords behind a wall for mounting a TV.  The absolute proper way to have a cordless look TV mount to code would be to have the electrical outlet right behind the TV or a power bridge (but $70 is steep).  However, we chose to run cords behind and down the wall (instead of installing an outlet) in case we do not want to have a TV in this spot in the future.  A hole will be much easier to patch than removing an electrical box.

Tools needed for the job:

• TV Mount
• Stud Finder
• 2 Low Voltage Boxes
• Torpedo Level - more accurate for small distances
• Pencil
• Impact/Drill
• Oscillating tool - Dremel Multi-Max or Rotozip (we used a Milwaukee Multi-Tool)
• 2 Brush Wall Plates

Step 1: Mount the TV Bracket following the manufacturer’s instructions.

Step 2: Pencil trace cut out placement for the upper low voltage box behind the TV.  Ensure the box is level.

Step 3: Cut out the tracing for the low voltage box. 

We have found the easiest way is to use a carbide blade for the plaster and a wood blade (or rotozip) for lath.  *If you have drywall a simple jab saw or rotozip will do the job*

Plaster:

Lath:

 Step 3 complete:

Step 4: Insert low voltage box ensuring the clips have a good grip behind the wall.

Step 5: Locate Placement for lower low voltage box.  A large level will do the trick. 

We got thrifty and used a weighted down string as a plumb-bob.

Step 6: Repeat steps 2-4 for installing the lower low voltage box.

Step 7: Install cover plate (brush wall plate) on upper and lower low voltage boxes.

Step 8: Enjoy a finished cordless look!
