INSTALLATION
E
xtension jambs for vinyl windows and patio doors are trim
components designed to attach to the interior side of the frame
and extend the frame width to fi t a 4 9/16" or 6 9/16" wall. We offer
two trim options: red oak or white vinyl wrap.
These extension jambs are designed to be attached to the window
prior to being installed in the wall. To replace extension jambs on a
unit already installed, skip these installation instructions and proceed
to the next page to the Replacement section.
Note: These instructions do not apply to the Colonial Series vinyl
windows.
