structural panel sheathing by at least 1/4 inch. Ensure that the
ring shanks of the fastener fully engage the wood structural
panel sheathing. (Diagram 3a)
• Fastener placement: A minimum 3/4 inch down from top edge
of siding. Fasteners shall be placed 1 inch from ends, excluding
the width of the shiplap. (Diagram 3a)
• Fastener spacing: Space ring shank nails a maximum of 8 inches
o.c. across the top of siding. (Diagram 4a)
• Use a minimum 0.092 inch diameter shank, hot-dipped
galvanized or stainless steel ring shank nail. Fasteners shall be
corrosion resistant and capable of preventing rust, stain and
deterioration under normal outdoor environmental conditions
for a period of no less than 50 years.

• For the cleanest cut and longer blade life, a ne-tooth carbide tipped blade is recommended.
• Siding is manufactured with a special edge coating which reduces moisture-related issues. If siding is ripped you must take
special care to prime, paint and seal all exposed wood ber as described in the nishing section.
• Climb cut the surface of the siding such that the rotation of the blade cuts downward on the primed or prenished surface.
• Do not miter edges.
