A device for leveling a longitudinally extended concrete form assembly including a ground-supported upright supporting beam wherein a block member for a threaded leveling screw is held in engagement with the upper surface of a lower end plate of the upright beam. The leveling screw is in axial alignment with a central throughbore of the end plate whereby on rotation of the leveling screw will extend and retract and lower end thereof relative to the bottom surface of the end plate to raise and lower the upright beam relative to the ground.
