Abstract
Abstract A merchandise shelf arrangement utilizing molded plastic shelves each of which has a corner arrangement with an open bore through which is fitted a respective vertical support member resting on the floor. Tapered plastic inserts removably placed between the vertical members and the respective bore of each shelf corner retains the shelf in a selected location ready for easy removal and re-positioning. Projecting lugs or tongues on each molded insert are fitted respectively into one of many vertically spaced locations on a vertical member to hold the tapered insert in place. Weight from a number of cartons of bottles or the like pressing downwardly on the shelf causes a tighter relationship between each insert and its respective corner to assure positive retention of each shelf. Each shelf is molded integrally with each corner arrangement in a pattern which may be in the form of an open grid structure reducing weight and is of plastic material and providing ventilation and drainage.
