Step 4: Square the Frame.

Place two - 2"x6" support boards on the 4"x4" post using the dimensions found on the plan. Attach the 2"x6" end board to each of the 2"x6" support boards using two - 2 1/2" deck screws at each connection. Using the same dimensions of the 2"x6" end board found on the plan, verify that the distance between the two - 2"x6" support boards are equal at both ends of the frame. Once the two - 2"x6" support boards are an equal distance apart from each other, "tack" a temporary board to the two 2"x6" support boards about 2 feet from the edge of the pool.

Tacking a Temporary Board: Use a 2"x6" surface board as a temporary board. Place the worst side up. Use two deck screws at each connection and only place the screws 80% of the way in (stop before the head of the screw penetrates the surface of the wood). Allow an equal amount of board to extend beyond the frame.

Next, measure the diagonal distance from opposite corners of the support frame. Adjust the 2"x6" support boards and Dek-Block® piers until the diagonal distance between opposite corners is EQUAL. Once the frame is square, toe-screw the 2"x6" support boards into the 4"x4" posts using two - 2 1/2" deck screws on each side of the 2"x6" support board.
