ABSTRACT:
A one piece suspended ceiling hook comprising an upper rail gripping portion and a downwardly extending hook portion. The upper portion includes two inwardly extending and opposing flanges having inner edges spaced apart from each other. A recess is formed within the upper portion with the inwardly extending flanges defining the upper border of the recess. The recess is adapted to receive a lower horizontal rim of a suspended ceiling beam. The upper portion is capable of flexing. Tabs extend outwardly and downwardly from the outer portion of the upper portion for manual movement to an inward position such that the upper portion flexes and the two opposing flanges move outwardly such that the inner edges of the flanges are a greater distance apart than the width of the lower rim of the suspended ceiling beam. The downwardly extending hook portion has edges which about the tabs when flexed to limit the extent the tabs can flex the upper portion.
