<p>A stackable metallic pallet collar in the form of a hollow rectangular frame which can be folded into compact form for storage. The collar consists of four side sections arranged in opposite pairs joined by means of hinged joints so that they can be folded together. The side sections are sheet metal and are provided with continuous longitudinal ribs arranged and dimensioned so that the longitudinal ribs of adjacent side sections which are connected by a common hinged joint nest within one another in pairs when the side sections are folded together around the common hinged joint. The upper and lower edges of the side sections are bent outwardly and down to permit stacking of the collars when extended.</p> |
