Wall Returns make it easy to add your own extension jambs. They are an alternative
to ordering factory applied extension jambs. Wall returns are a U-shaped channel,
factory applied to the window frame. Choose the width of the Wall Return based on
the material you plan to use. For example, if you plan to use ½” drywall, choose ½”
wall returns. If you plan to use ¾” thick wood, choose ¾” wall returns.
