The Clifton is an 8" tall block that has a rear lip system that provides a 3/4" backset which makes it a quicker and easier installation. It is a gravity retaining wall which means it needs no pins or clips to install it. By not needing any clips or pins it also saves time and money without having to buy extra parts or install other items into the wall. The Clifton is also lighter than the competitors block with a hollow core design that not only eases installation but helps with drainage and connection between the units when the cells are properly filled with crushed rock or pea gravel. When planning a project with the Clifton it is also very easy to estimate how many you need because each block is one square foot. These block are designed for residential, commercial and industrial type applications and can be engineered to be higher than 4'. These are available in 3 colors - gray, tan, and sienna and 2 different styles - beveled and straight face.
