How to Build a 4 Post Rack

4 post rack can add storage and organizational space to any room. Making one yourself can be a cost effective way to add one to your room. They can be free standing or can be inserted into a closet to store clothing.

Clothes racks are typically used to hang up clothing items such as jackets, coats, shirts, pants and dresses. They can be used solely or in addition to existing closets in a room. Clothes racks can also be used for drying wet clothes.

By following the steps below, you can easily build a 4 post rack. The tools needed include:

  • Power drill with drilling and screwdriver drill bits
  • Hammer or pneumatic nailer
  • Wood glue
  • Measuring tape
  • Pencil
  • 4 1-by-16-by-4 foot wood boards
  • 1 20-by-20-by-1 foot wood board
  • 1 1-by-1-by-3 foot wood beam
  • 2 1-by-1-by-4 foot wood beams
  • Finishing nails
  • 3 1-inch wood screws
  • 6 pegs with round heads

Step 1 – Build the Base

Start your 4 post rack by creating a frame by using the 4 1-by-16-by-4 foot wood boards. Secure them in place with the wood glue. Next, glue the 20-by-20-by-1 foot wood board to the frame. Allow the wood glue to dry.

Step 2 – Secure the Joints

Using a hammer or pneumatic nailer, hammer in the finishing nails to secure each of the joints of the frame. Also use the nails to attach the 20-by-20-by-1 foot wood board securely.

Step 3 – Find the Center

Turning the base upside down, use your measuring tape to find the center point of a board and mark the point with your pencil. Drill a small pilot hole through the mark. Line up the end of the 1-by-1-by-3 foot wood beam with the hole and use one of the wood screws to join the wood beam to the base.

Step 4 – Drill the Beams 

In one of the 1-by-1-by-4 foot wood beams, drill a 1/8-inch deep hole. On the remaining wood beam, drill 5 evenly spaced holes that are also 1/8-inch deep. These holes should be large enough for the pegs to fit, so make sure to choose an appropriately sized drill bit. Put a drop of wood glue in each of the holes and insert the round head wood pegs. 

Step 5 – Attach the Beams 

Using the wood screws, attach the wood beams toe the edge of the 3-foot beam, placing one of the beams 1 inch higher than the other. 

Building and Design Tips 

Make sure to let the wood glue dry when building the frame as well as prior to hanging anything from the wood pegs. This will allow the rack to be its most secure for use.

To give your 4 post rack a finished look, you can use paint, a stain or a laminate. Make sure the rack is completely dry before adding any clothing to avoid staining.
