fastening procedures
Step 1 
Make sure the bottom lock of the 
panels are fully engaged along 
the entire length of the panel. 
WARNING: Push the panel up fully 
but do not stretch the panel by pulling 
it from the top.
Step 2 
Do not drive the head of the fastener 
tightly against the siding nail hem. 
Leave a minimum of 1/32˝ (the  
thickness of a nickel) between the  
fastener head and the vinyl. Tight  
nailing, screwing, or stapling will 
cause the vinyl siding to buckle with 
changes in temperature (Fig.1).  
If the head or crown contacts the 
vinyl panel it may “pimple” or distort 
due to heat build-up.
Step 3 
After locking the panel, fasten the 
panel in the center, work in, to both 
ends.This method helps keep panels 
running straight.
Step 4
Nail 8˝ or more away from the end of 
a panel that will be overlapped with 
another panel. This will help the over-
lap appearance. 
Center the fasteners in the slots to  
permit expansion and contraction of 
the siding (Fig. 2).
Step 5
Drive fasteners straight and level to 
prevent distortion and buckling of  
the panel (Fig. 3).
Step 6 
Space the fasteners a maximum of 
16˝ apart for horizontal siding panels, 
12˝ apart for vertical siding panels, 
and 8˝ to 10˝ apart for the accessories. 
Step 7 
Start fastening vertical siding and cor-
ner posts in the top of the upper-most 
slots to hold them in position. Place 
all other fasteners in the center of the 
slots (Fig. 4).
Vinyl siding can expand and contract 1/2˝ or more over a 12´ 6˝ length 
with changes in temperature. Whether using a nail, screw or staple to 
fasten the siding, the following basic rules must be followed:
