About half the size of the Standard unit, Cobble units are perfect for planters, small walls and garden-variety projects as well as large, expansive commercial and governmental walls. Smaller and conveniently lighter than its big brother Standard unit, a Cobble unit possesses durable characteristics equal to units twice its weight. Of course, Cobble units use the same top-down pinning systems as other VERSA-LOK units, saving you time and installation costs.   COBBLE UNIT MEASUREMENTS HEIGHT   6" (152.4mm)     WIDTH (FACE)   8" (203.2mm)     WIDTH (REAR)   6" (152.4mm)     DEPTH   12" (304.8mm)     FACE AREA   1/3 sq. ft.
