Abstract: A merchandise display hook 20 comprising a downward recess 24 for engagement with a horizontal bar material b, a first groove 32 provided substantially horizontally and substantially orthogonal to the bar material b at the upper surface 21, a first fixing orifice 38 provided substantially perpendicular to the bottom portion of the first groove 32, a second groove 42 provided substantially vertically and substantially orthogonal to the bar material b at the rear surface 23, and a second fixing orifice 48 provided substantially horizontally on the bottom portion of the second groove 42, the hook being substantially entirely composed of a synthetic resin. With such a hook, the number of arms can be easily adjusted with a small number of components, the number of production processes and cost can be reduced, and the merchandise arrangement can be changed rapidly.
