Step 16: Attach handrail boards.

Along the Splash deck, measure the distance from the inside edge (edge closest to the pool) of the 4"x4" post to the inside edge of the adjacent 4"x4" post. Mark and cut a 2"x6" board using the same degree angle as the Support Frame board at each end (typically 10 or 7 1/2 degrees). Place the 2"x6" board 1 1/2" below the desired height of the rail. Attach the 2"x6" boards using two 2 1/2" deck screws at each end. One from the top of the 2"x6" board into the 4"x4" post and one from the bottom of the 2"x6" board into the 4"x4" post inserted at an angle (toe-screwed).

Along the Deluxe portion, measure the distance between the 4"x4" post to the inside edge of the adjacent 4"x4" post. Cut a 2"x6" board to length. Place the 2"x6" board 1 1/2" below the desired height of the rail. Attach the 2"x6" boards using two 2 1/2" deck screws at each end. One from the top of the 2"x6" board into the 4"x4" post and one from the bottom of the 2"x6" board into the 4"x4" post (toe-screwed).

Use the same measurements and angles as the 2"x6" rail boards, and cut a horizontal 2"x4" board. Position the 2"x4" board on top of the 2"x6" rail board and secure with 2 1/2" deck screws approximately every 16 inches.
