Place a ladder or a step stool underneath the ceiling area where you want to install the ceiling hook.
Climb up until you can reach the ceiling and use a stud finder. Place the device flat on the ceiling and slide it until the location of a ceiling joist is indicated. Mark the location with a pencil.
Continue sliding the stud finder to the left or the right. When you locate another joist, draw another mark on the ceiling; this is the end of the joist.
Don safety glasses and insert a 1/4-inch bit into a drill. Place the tip of the bit on the ceiling between the two marks. Squeeze the drill trigger to create a 1-inch-deep hole in the ceiling.
Insert the threaded end of a hook, which resembles a screw, into the hole and turn it clockwise to insert the threads into the hole in the ceiling joist. Once you can no longer hand-tighten it, twist it another half turn using pliers.
Hang the desired object on the bottom of the hook.
