1. A structural framing system comprising an expandable support member having an outer support member and an inner support member attached to a plurality of connector members comprising:
said outer support member having an outer web attached to a first outer flange extending away from said web, said first outer flange attached to a first lip extension said outer web attached to a second outer flange extending away from said web, said second flange attached to a second lip extension together forming a C-shaped configuration having an outside planar side and an inside planar side, and having a first end and a second end; said inner support member having an inner web attached to a first inner flange, said inner web attached to a second inner flange together forming a U-shape configuration with the configuration having an outside planar side and an inside planar side, and having a first end and a second end, said outer support member at said inside planar side extends around the outside planar side of said inner support member secured by friction between said inside and outside planar sides to said inside planar side of said outer support member;
said outer support member has an outside aperture cut into said outer web setback from the second end of the outer support member and said inner support member has an inside aperture cut into an inner web setback from the first end of the inner support member, said outside aperture and said inside aperture overlap and are aligned horizontally forming an overlapping aperture, each said inside aperture and said outside aperture has a first perimeter side edge and a second perimeter side edge opposite said first perimeter side edge, and a third perimeter side edge opposite a fourth perimeter side edge being a bottom perimeter edge, said first perimeter side edge and said second perimeter side edge has an array of perimeter hole notches cut into said first perimeter side edge and cut into said second perimeter side wall edge, the first perimeter hole notches at said outside aperture are aligned with the perimeter hole notches at said inside aperture, enabling said first and second perimeter hole notches at said outer support member to be offset from said first and said second perimeter hole notches at said inner support member by adjusting height variation positions between said perimeter hole notches at said inside and said outside apertures;
said overlapping aperture enables a first one of the connectors to engage with aid first and said second perimeter hole notches; said one of the connectors has a connector web attached to a first connector flange, said connector web attached to a second connector flange, said connector web having a first end with a cut into said connector web forming a first connector web notch to engage said first perimeter hole notches, said connector web having a second end with a cut into said second connector web notch forming a second connector web notch to engage said second perimeter hole notches at said overlapping aperture, or
a second one of the connectors having with a connector web an attached to a first connector flange with an extending first connector flange, said connector web having an attached opposing second connector flange with an extending second flange, said extending first connector flange has a flared distal edge with a first connector notch cut into the distal edge, said extending second flange having a flared distal edge with a second flange connector notch cut into the distal edge, said second one of the connectors has a first end and a second end, said first and said second flange connector notch setback from said first end and said second end enable to engage said overlapping aperture at said expandable support member; or
a third one of the connectors having a perimeter hole notch connection having a first flange with an attached first lip having a cut into a distal edge forming a first lip notch, said third connector having a second flange with an attached second lip having a cut into the distal edge forming a second lip notch, said first and said second lip notch setback from the first end and the second end to engage said overlapping aperture at said expandable support member.
