  • The steel must be 16 or 18 gauge.
  • The holes must be pre-drilled oversized using a 9/32” carbide tip drill bit with the center screw being the fixed point using a 7/32” carbide tip drill bit.
  • Remember to install the center screw first then continue in a spiral.
  • The screws must not be over tightened. Over tightening the screws will restrict the panel’s movement & will cause cracking.
  • The spacers may never be longer than 10’.
  • There must be a 1/2” gap between the spacers.
  • There should be 21 screws in a 4’x 8’ board.
  • There should be 24 screws in a 4’x 10’ board
