ABSTRACT:
The invention disclosed shows a device, method and system for installing threaded masonry anchors. A plate is used to control the rate of axial penetration of the anchor into a masonry structure. An opening in the plate allows engagement of the anchor with the plate. Rotation of the plate is prevented by various means. As the anchor advances and forms threads in the structure, the plate may be used to resist axial forces on the anchor in either axial directions thereby precluding stripping of threads formed in the masonry structure.
