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
- 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*
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!
