The bottom channel and side channels are connected to the new sill and new side jambs of a new prime window unit and the top channel is extended between the upper ends of the side channels. Each channel includes an inner wall extending exteriorly of the new prime window unit for recessing it relative to the frame and an outer wall extending outwardly from the new prime window unit. The outer walls are provided with a plurality of spaced apart slots for reducing the width of the channels to fit various window sizes.
The method of the invention includes connecting the bottom channel and side channels to the sill and side jambs of a new prime window unit, connecting the top channel across the upper ends of the side channels and placing the preassembled new window unit and channels into a window unit opening.
