"Hook and Line" equipment is commonly used by first responders to move suspicious packages from random locations to a safe container or location. Within buildings constructed with wallboard, wall anchors for guiding the line are typically mounted by punching through the wall board or adhering to it, either way causing considerable damage and not providing a very secure anchor. The device of the invention bores a neat circular hole in the wallboard, which is easily repaired. The device also uses pivotal grips which reach inside the hole, the wallboard being clamped between these grips and an outside adjusting ring or shoulder of the anchor. This provides a secure anchor which is easily removed when the task is complete.
