Roller bar security device and fence

摘要

A roller bar security device includes a longitudinally extending tubular member having first and second ends and a plurality of rigid overlapping outwardly extending blades each of which has a generally triangular shape with a base mounted on the tubular member and a sharp point at its apex. The blades are fixed to and extend around and along the tubular member with the apexes of alternate longitudinally spaced blades facing in generally opposite directions. A mounting bracket and bearing are provided for rotatably mounting the tubular member and blades on top of a wall or the like so that the sharp points and edges will deter a potential intruder from climbing over the security device.
