Plastic Utility Shelving Unit Parts and Panels Lot

Multiple plastic shelving unit components, including flat panels and hollow cylindrical support tubes. Images show at least four rectangular panels with molded corners, intended for use as shelves, along with several plastic support tubes of varying diameters. The panels appear stackable and interlocking, compatible with typical modular utility shelving systems.  Some panels display minor wear and surface marks. No complete assembly is shown, and assembly hardware is not visible. See photos for measurements, if taken. Carefully review images to confirm specific parts included.
