In a storage rack comprising a front beam and a back beam, a roller track comprises two side rails and a series of rollers defining a tangent plane. A front hook, which is hooked over the front beam, defines a ledge projecting backwardly. A back hook, which is hooked over the back beam, defines a ledge projecting frontwardly. At each end, each side rail is supported on the ledge of the hook at that end. Each hook has a flange projecting upwardly from its ledge, between the side rails, so as to limit lateral movement of the roller track. Comparatively, the front hook is taller and the back hook is shorter, whereby the roller track can be easily inclined.
