ABSTRACT:
A device for moving a wall frame unit into an erect and plumb position includes a pulling unit mounted on one wall frame unit and a pulled unit mounted on the wall frame unit to be erected. A cable unit connects the pulled unit to the puller unit via a lock handle on the puller unit. Movement of the puller unit handle into a prone position draws the cable unit towards the puller unit. A differential pulley block is included so that one worker can, without assistance, move the second wall frame unit.
