Step-by-Step Instructions

1

Determine weight and plan accordingly

5 minutes

Check the weight of your TV or mirror. Under 20 lbs can use standard picture hangers. 20-50 lbs needs heavy-duty anchors or one stud. Over 50 lbs REQUIRES mounting to studs.

Warning

TVs and heavy mirrors can cause serious injury if they fall. Don't take shortcuts with mounting hardware.

2

Choose optimal height

5 minutes

For TVs: center of screen at eye level when seated (typically 42-48 inches from floor). For mirrors: center at average eye level (about 57-65 inches), or lower for specific uses.

Pro Tip

Mark the center point where you want the TV/mirror, not the top of the mount.

3

Locate studs

5-10 minutes

Use a stud finder to locate and mark studs in your mounting area. Mark both edges of each stud. You'll need to hit at least 2 studs for heavy items (TVs over 50 lbs).

Warning

For heavy items, studs are NOT optional. Don't rely on drywall anchors alone.

4

Mount the wall plate (TV) or cleat (mirror)

15-20 minutes

For TVs: hold the mount's wall plate against the wall, level it, and mark holes. Drill pilot holes into studs, then drive lag bolts through the mount into studs. For mirrors: install the wall half of a French cleat, driving screws into studs.

Pro Tip

Have a helper hold the mount while you level and mark - TV mounts are heavy.

5

Verify mount is secure and level

5 minutes

Tug firmly on the installed mount - it should feel rock solid. Check level again. Tighten any loose bolts. The wall mount must be completely secure before adding the TV or mirror.

6

Attach mounting hardware to TV/mirror

10 minutes

For TVs: attach the mounting brackets to the back of the TV using the provided hardware (follow mount instructions for your TV size). For mirrors: attach the mating half of the French cleat to the mirror frame.

7

Hang the TV or mirror

5 minutes

Lift the TV/mirror and hook onto the wall mount. TVs typically hook onto the wall plate and may click into place. Mirrors slide down onto the cleat. Have a helper for heavy items.

Warning

Get help for heavy items - lifting while reaching is a recipe for back injury or dropped equipment.

8

Level, adjust, and secure

5 minutes

Adjust the TV on the mount if it allows. Check that it's level. Tighten any security screws. For mirrors, adjust position on cleat. Add adhesive bumpers to bottom corners to hold position.

Common Mistakes to Avoid

  • Not finding studs for heavy items
  • Underestimating weight
  • Using inadequate hardware (picture hooks for heavy items)
  • Not using a level
  • Single stud for very heavy TV

Safety Warnings

  • Get help lifting heavy TVs and mirrors
  • Wear safety glasses when drilling
  • Check for electrical wires before drilling (use a wire detector)

When to Call a Professional
