ABSTRACT:
A door frame aligning system having a squaring system which includes a reel and guides securable at the four corners of a door frame. A line extends from the reel about the guides in criss-cross fashion. If the door frame is square and planar, the line will lightly intersect in the center of the frame opening. The second part of the system is a threshold spreader which is attachable across the threshold to adjust the opposite jamb frame member to a precise parallel position.
