An adjustable beam holder to be used with parallel spaced apart forming boards. The holder includes an elongated case with a longitudinal and centrally disposed slot that receives an elongated removably mounted connector member with an elongated protruding platform member on one side and the opposite side having perpendicularly mounted walls that are removably attached to the slot. Headed threaded shank members are inserted inside the case through openings defined by removable tabs formed on removable cap members mounted to the ends of the case. Readily detachable arms are mounted to the connector mounted to the case member in order to rest over the edges of forming wall and thereby aligning the upper wall flush with the plane defined by the upper edges.
