Category: Installation Guides

Reading Time: 7 minutes

Installing a TV wall mount with in‑wall cable management creates a clean, modern, cable‑free look. This guide walks you through the full installation process — mounting, routing cables, installing power relocation kits, and final alignment.

Tools & Materials Needed

• Stud finder

• Level

• Drill + drill bits

• Drywall saw

• Phillips screwdriver

• Socket wrench

• TV wall mount

• Lag bolts

• In‑wall cable management kit

• Power relocation kit (if applicable)

• HDMI cables

• Painter’s tape

• Pencil

Safety Notes

• Always mount into studs, concrete, or masonry — never drywall alone.

• Use UL‑listed in‑wall rated cables for safety.

• Turn off power before installing any power relocation kit.

Step 1: Choose the TV Height

1. Determine the ideal viewing height (typically 42–48 inches to center).

2. Mark the approximate center point with painter’s tape.

3. Confirm the height works from your seating position.

Step 2: Locate the Studs

1. Use a stud finder to locate two studs.

2. Mark the center of each stud with a pencil.

3. Use painter’s tape to create a straight horizontal line.

Pro Tip: Mounting across two studs provides maximum stability.

Step 3: Position the Wall Mount

1. Hold the mount against the wall.

2. Use a level to ensure it’s perfectly straight.

3. Mark the drill hole locations.

Step 4: Drill Pilot Holes

1. Use a drill bit slightly smaller than your lag bolts.

2. Drill into the stud marks you made earlier.

3. Keep the drill level to avoid angled holes.

Step 5: Install the Wall Mount

1. Align the mount with the pilot holes.

2. Insert the lag bolts.

3. Tighten using a socket wrench until snug — not over‑tightened.

Step 6: Cut Openings for Cable Management

1. Use the templates included with your in‑wall kit.

2. Trace the top and bottom openings with a pencil.

3. Cut the openings using a drywall saw.

4. Ensure the top opening is directly behind the TV mount.

Step 7: Install the In‑Wall Cable Kit

1. Insert the top and bottom grommets or brush plates.

2. Feed HDMI and other low‑voltage cables through the wall.

3. Pull the cables out through the bottom opening.

4. Ensure cables move freely with no pinching.

Step 8: Install the Power Relocation Kit (If Included)

1. Turn off power at the breaker.

2. Install the upper and lower power boxes.

3. Connect the included power cable between them.

4. Restore power and test the outlet.

Pro Tip: This keeps everything code‑safe and avoids exposed power cords.

Step 9: Attach the TV Brackets

1. Lay the TV face‑down on a soft surface.

2. Align the mounting arms with the VESA holes.

3. Secure using the included screws.

Step 10: Hang the TV

1. Lift the TV and hook the brackets onto the wall plate.

2. Ensure both sides lock into place.

3. Connect HDMI and power cables.

4. Adjust tilt or swivel if your mount supports it.
