Many of the wall block styles available from RCP Block & Brick are based on a pinned system. These fiberglass or molded pins are used to both align and secure the block courses to one another. The above video explains the benefits of using a pin system as well as how to properly insert the pins. Using the different pin holes, you can accomplish a set-back wall or true verital wall.
