If you are going to make and install your own shutters, take the time to pre-install the anchorage hardware and prepare your shutter materials before a storm threatens. 

• Pick out and purchase the plywood material you want to use.
  • IBHS recommends 5/8-inch plywood as a minimum standard.
• Purchase the appropriate quantity of steel hanger bolts.
  • Anchor spacing:
    • No. 8 wood screw-based anchors should be spaced:
      • 8 inches apart for 6 to 8 foot panels
      • 10 inches apart for 4 to 6 foot panels
      • 16 inches apart for smaller panels
    • No. 10 wood screw-based anchors should be spaced:
      • 9 inches apart for 6 to 8 foot panels
      • 12 inches apart for 4 to 6 foot panels 
      • 16 inches apart for smaller panels
  • Lag screw-based anchors should be spaced 16 inches apart for all panel sizes up to 8 feet.  
• Cut the plywood to fit each of your home’s windows.
• Use the wood grain as your guide for placing the fasteners.
• Placing them perpendicular to the grain will ensure proper strength.
• Install the hangers so that you achieve a minimum embedment depth of 2 inches into the wood framing within the wall.
