Abstract: An improved apparatus for defining a mold to allow the pouring of a concrete wall therein is disclosed along with a method of use thereof wherein two identically configured panel members each define slots therein which receive flanges of a connecting member. The connecting member is designed to be placed into the slots in the panel members at the site of construction thereby allowing shipment of the panel members as well as the connecting members to the construction site collapsed or packaged in a compact manner. The connecting member includes a central spacer mid section which can be configured having various lengths in order to accommodate forming of concrete poured walls of different thicknesses based upon the decision made at the site of construction.
