About half the size of the VERSA-LOK Standard wall block, Cobble units are perfect for planters, small walls and countless garden-variety projects. Smaller and conveniently lighter than its big brother Standard unit, versatile Cobble wall units retain the same top-down pinning system, saving you time and installation costs.
