Keystone Country Cottage

The 4" Keystone Country Cottage Tumbled Gravity Stacked System is designed to be built to a maximum height of 20 inches. This wall system does not have pins or a lip and is designed to be "dry stacked" for planter box type applications. It is strongly recommended that a 50/50 combination of Large and Small units be mixed randomly in the wall to maximize the stability and strength of the wall.
