Abstract
A method is described of making a plurality of window frame members having different end use applications on a single production line. The method comprises the step of extruding from a single die plate a master window frame member having at least two flange portion extending therefrom. The method also comprises the step of cutting at least one flange portion at a predetermined location to create a functional frame member having a specific end use application.

A method of making a plurality of window frame members having different end use applications on a single production line, comprising the steps of:
- extruding a plurality of master window frame members during at least first and second production runs from a single die plate, each of said master window frame members having at least two flanges extending from a wall facing side of said master window frame member;
- selectively cutting during said first production run a substantial portion of at least one flange from a first master window frame member from said plurality of master window frame members at a predetermined location to create a new construction window frame member having a nailing flange;
- and
- selectively cutting during said second production run on said single production line a substantial portion of at least one flange from a second master window frame member from said plurality of master window frame members at a predetermined location to create a replacement window frame member not having a nailing flange.
A master window frame member extruded from a single die plate, said master window frame member comprising at least two flanges extending from a wall facing side of said master window frame member,
- said flanges being configured such that a first substantial portion of at least one of said flanges may be selectively cut at a predetermined location on said master window frame member to produce a new construction window frame member having a nailing flange and a second substantial portion of at least one of said flanges may be selectively cut at a predetermined location on said master window frame member to create a replacement window frame member not having a nailing flange.
A method of making a plurality of window frame members having different end use applications on a single production line, comprising the steps of:
- extruding a plurality of master window frame members on said production line during at least first and second production runs from a single die plate, each of said master window frame member having at least two flanges including a flush fin flange and a nailing flange extending from a wall facing side of said frame member;
- on said single production line, selectively cutting during said first production run a substantial portion of at least one flange from a first master window frame member from said plurality of master window frame members at a predetermined location to create a new construction window frame member having a nailing flange with at least a substantial portion of said flush fin flange being removed;
- and
- on said single production line, selectively cutting during said second production run a substantial portion of at least one flange from a second master window frame member from said plurality of master window frame members at a predetermined location to create a replacement window frame member with at least a substantial portion of said nailing flange being removed.
