JELD-WEN SIV001 Extension Jamb for Vinyl Windows and Patio Doors User Manual

Installation

INSTALLATION

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.
