Tools Needed 

  • Saw
  • Screw gun 
  • #2 Phillips-head bit 
  • Tape measure 
  • Clamps
  • Framing square 

Installation Instructions 

  1. Cut lumber and plywood to size. Since all of your cuts are straight cuts, Simpson Strong-Tie connectors simplify building with wood.  
  2. Install connectors on vertical posts: Mark height, clamp connector to post, and attach with Simpson Strong-Tie® #8 x 1 1/4″ wafer-head screws. No predrilling is needed.  
  3. Connect horizontal rails on each side: Use a clamp to help hold the wood in the seat of the connector during installation.
  4. 4. Notch corners of plywood shelves: Use a piece of 2×4 on each corner of the shelf, trace, and cut to accommodate corner posts (only notch back corners of top shelf).
