Step 25: Rock Wall Assembly
•
The rock wall is typically made slightly longer than required to allow for a slope
•
Place the rock wall against the top of a closed railing
•
Measure the amount you may have to take off the bottom of the rock wall
•
Cut the bottom of the rock wall to ensure that it fits flush onto the top of the top rail
•
Screw the rock wall into its place using 2 x 65mm screw per board, ensuring you predrill the
holes to avoid splitting the timber
