 Do not over drive the fasteners. Seating them below the surface of the siding
reduces their holding power. Do not place fasteners in the center, unsupported
area of the siding.
 If you are hand nailing, it may be necessary to predrill to help prevent the corners
from breaking.
 Fasten from one end of the panel to the other.
Installing Octagons and Half-Rounds on Walls with Gable Ends
For best appearance, gable installations should end with a single Half-Round or
Octagon at the peak.
1. Measure the height of the gable/wall (in inches).
2. Divide the height of the gable/wall by 7”.
3. If the answer is an even number, center the first course of Half-Rounds or
Octagons on a keyway.
4. If the answer is an odd number, center the first course on a Half-Round
or Octagon.
