Abstract: A construction tool to facilitate tie rod and key plate installation onto concrete forms, primarily comprising a housing and an extraction assembly. The extraction assembly having means to slidably journal generally within the housing. The housing has a movable plate assembly at one end that has a protrusion outwardly extending therefrom. The protrusion is uniquely shaped to mount a key plate thereon. Additionally, the housing has brackets mounted at opposite sides of the movable plate, which provide space for the extraction assembly to mount onto the end of a tie rod. Operationally, a key plate is mounted onto the protrusion, said invention is placed onto the approach side of a concrete form, and an extraction head of the extraction assembly is placed onto the tie rod end and pulled sufficiently to allow placement of the key plate onto an interlocking notch of the tie rod, thus securing the concrete form.
