Lay the towel closet frame across a wide, flat work space so that all parts are visible and in place. You should see towel bars that run in a vertical row much like a ladder and two wide hooks at the top of the frame.
Place a step stool near the base of the door and on the side of the door you would like to install the towel frame.
Pick up the towel frame by the two hooks at the top.
Climb the step stool and place the two hooks over the top of the door. Gently lower the rest of the towel closet frame onto the door. Place towels on the vertical rods.
