Abstract: A framing system for a building, house, storage cabinet, or the like employing a plurality of novel structural members or clip-in-joists and a plurality of other structural members, such as channels, I-beams, or the like. The clip-in-joists are special channel members or extrusion joists which have a slot or cut in each leg thereof opposite each other and near the end of the joist. The slotted end section of the joist is adapted to be inserted or snapped-in a second structural member, such as an I-beam or channel member or other structural member having a similar receiving configuration. The member is preferably made of structural aluminum, but can also be made from metals such as iron, steel and the like or plastics such as PVC, ABS, styrene and the like. A wide variety of structural materials may be used, depending upon the particular requirements of the end or resulting construction.
