Using Iron Neck at home or at the office is easy with the Safe Lock Door Anchor.
Instructions: Open door. On the door hinge side, weave the door anchor's D-ring between the door frame and door. The knot of the door anchor should jam. Close door and make sure the knot is pressed firmly by pulling on the D ring. Always ensure door and anchor position are secure. Periodically check all components for wear. If wear is present, replace.
