Abstract: Stackable display bins for supporting quantities of cylindrical articles such as tubes of caulk and the like have U-shaped interiors that are accessible through U-shaped front openings. The bins have generally rectangular front, rear and side walls that connect with a symmetrically curved bottom wall to define their U-shaped interiors. The front, rear and side walls extend substantially vertically so they can directly underlie and overlie the front, rear and side walls of other identically configured bins in a vertically stacked array of bins. Removable extenders connect with the bins near front ends of the right and left side walls for pivotally mounting doors at locations spaced forwardly from the U-shaped openings for supporting signs that identify the contents of the bins. Methods of utilizing single bins and pairs of bins with short and long doors and removable interior partitions to display quantities of relatively large and relatively smaller sized tubes of caulk also are disclosed.
