The invention provides a "change of direction" device for use by a law enforcement technician. The device can be readily and easily attached to a building element and will allow the technician to pass a rope, wire or cable therethrough so that the rope, wire or cable can be pulled by the technician after one end has been attached to a hazardous item of concern. The change of direction device (CODD) would be positioned within the building at strategic locations where it is clear that the item of concern will have to change directions as it is being pulled from the location at which it was found. The invention provides several embodiments of the CODD for attachment to a wall, to a door hinge, or under the bottom edge of a door. Each CODD is simple in construction and is of such a nature that it can be positioned at the desired location without any preparation having to be done. In the case of the door and hinge CODD's they can be removed at a later point in time for re-use if necessary.
