Abstract
A security device includes a housing containing a ratchet mechanism and a rotatable spool for storing a plurality of cable loops which extend outwardly from a plurality of openings formed in the housing and wrapped around the sides of a box-like object. A collar is mounted on the bottom of the housing and has openings adjacent each of the housing opening requiring the cable loops to abruptly change direction after exiting the housing and passing either beneath or above the collar before extending along the secured object. This abrupt change of direction reduces the amount of force which are exerted on the cable loops from being transmitted onto the ratchet mechanism. In alternate embodiments, adjacent cable loops pass through one or a pair of rings which cause a change of direction in the cable loops to reduce the transmission of forces onto the ratchet mechanism.
