Each vertical support includes a longitudinal slot formed therein that has a keyhole cross section the longitudinal slot to receive a head end of the pin fitted to travel therein, which pin head end is an end of a threaded shaft to extend through a narrow section of the slot, at a right angle, into the showcase. A sleeve, that has a smooth wall center longitudinal passage formed therethrough, is disposed over the threaded shaft, and a cylinder, that includes a threaded center longitudinal passage formed therethrough, is arranged for turning onto the threaded shaft. The cylinder is to urge the sleeve along the threaded shaft to where a sleeve forward end will engage and bind against the vertical support along the slot, locking thereto. In practice, a plurality of pins are each positioned and secured at a like height along the vertical supports for maintaining corners and/or edges of a showcase shelf positioned thereon.
