Step 1 - Layout Dek-Block Brand Piers

Start by placing the two outside rows of Dek-Block brand piers to form the inside rectangle of the octagon. If the Dek-Block brand piers do not sit level, you may need to remove a little grass or dirt to level each Dek-Block brand pier. Space according to dimensions on plan.

Step 2 - Level First 2"x6" Support Board

Locate the highest corner Dek-Block brand pier. Position a 2"x6" support board in or above block to your desired height. Measure the distance from the bottom of the 2"x6" support board to the pocket of the Dek-Block brand pier. Cut 4"x4" post to length and position 2"x6" support board atop. Using a level as a guide, position the 2"x6" support board above the last block of the row. (Image 1) Measure the distance from the bottom of the 2"x6" support board to the pocket of the Dek-Block brand pier. Cut 4"x4" post to length and position 2"x6" support board atop. (Image 2) Repeat this process for all of the Dek-Block brand piers along this 2"x6" support. After all 4"x4" posts are cut and positioned, verify the support is level and make any adjustments that maybe needed.

Step 3 - Level Second 2"x6" Support Board

Temporarily remove the beginning 2"x6" support board and turn it 90 degrees. Using the 2"x6" support board as a level guide, determine the height of needed 4"x4" post for the remaining two corners of the rectangle. (Image 3) Measure the distance from the bottom of the 2"x6" support board to the pocket of the Dek-Block brand pier. Cut 4"x4" post to length. Repeat Step 2 for the second outside 2"x6" support board of the rectangle.

Step 4 - Create the Box

Attach 2"x6" end boards to the 2"x6" support boards using two 2 1/2" galvanized deck screws at each end. Using a level as a guide, ensure that both end boards are level. Adjust outside support boards until diagonal distance between opposite corners is EQUAL. This will ensure the frame is square. (Image 4)
