Step 5: Square the Frame.

Place a 2"x6" support board on top of each row of Dek-Block® piers. Attach 2"x6" end boards to the support boards using two 2 1/2" deck screws at each connection. The 2"x6" end boards will extend past the two 2"x6" support boards. Make sure the end board extends equally on either side. Using a level as a guide, ensure that both end boards and both support boards are level. Measure the diagonal distance from opposite corners. Adjust the support boards and Dek-Block® piers until the diagonal distance between opposite corners is EQUAL. After the deck is square and level in all four directions, attach the 2"x6" support boards to the 4"x4" posts using two 2 1/2" deck screws at an angle from each side (toe-screw).
