  • A screwdriver

Studs are like wood battens that support the walls and hold the weight. Use a metal stud finder to locate the stud, but it’s pretty much difficult to get the result, because of the horizontal strips and plaster. When you can detect something with the stud finder, use the earth magnet to locate the stud by gliding it up and down.

If there’s a socket board on the wall you don’t need these tools to locate the missile of the studs because the socket board is placed just in the middle of the stud. Measure 16 or 20 inches from the middle of the socket board to find another stud to mount the tv on. if you get the socket board out, you’ll get a slight view of the back of the plaster wall and you can locate the studs properly.

Place the leveler just on top of the mount and check the capsule’s bubble if it’s in the middle .tilth the mount along with the leveler to get the exact positioning. Once you found it holds the mount tightly and marks out the screw hole location with the pencil.

Step 3: DRILL the Marked Holes

Use the power drill driver to make holes in the middle of the stud. Make sure you drill in the middle of the stud because if you drill in the corners, the spring toggles won’t be attached properly. If you feel steady pressure against the drill while drilling that means you have found the stud. Drill all marked points throughout the stud.

Step 4: ATTACH the Spring Toggles

Now you have successfully made a hole through the stud, put the spring toggles inside the wall with the hammer, and then use a screwdriver to disclose the dagger of the toggle To secure the screw with the stud. Always choose the screwdrivers one size bigger than the drill so it stays tangible e with the wall.

Step 5: MOUNT the TV

When you have finished putting all the spring toggles, put the mounted brass on it and check that it won’t come off .try adding some pressure with your hand and tilting it to be sure it has firmly fitted with the screw. Put the tv on the mounted brass and angle it properly to enjoy it from a distant view.
