Massive is the word. This massive planter barrier from Stone-Cast is incredible. This was designed BY the U.S. Military FOR perimeter security on military bases around the country. A great
combination of security and aesthetically pleasing in a barrier. Remember BIGGER is BETTER. The walls of this planter are reinforced with 1/2" rebar welded cage with the top of the wall being 3"
thick to 5" thick at the bottom. This planter has forklift knockouts for easy deployment, elevated drain holes, beveled edges and an attractive exposed aggregate finish of your choice.
