Therma-Tru Fiber-Classic, Smooth-Star manual Interior Casing Attachment

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 1-½" 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 standard two-panel systems.

For manual application, we suggest using 4d-1-½" 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.
