INTERIOR CASING ATTACHMENT
Interior casing may be attached to the frame in either of the following ways:
An air nailer can be used to fasten the interior casing to the frame using 0.050 x
1-1/2 wire brad nails through the casing and fiberglass frame. For maximum
holding power, ensure that nails are installed through anchor blocks located within
frame profiles. Locations are shown below.
For manual application, we suggest using 4d-1-1/2 finish nails. They can be used
to secure interior casing to the frame. Pre-drilled pilot holes (1/16 dia.) are
recommended to avoid splitting casing or frame. Ensure that nails are installed
through anchor blocks for maximum holding power.
