True stack modular stone

Ply Gem Stone True Stack modular stone provides a dry stack style with time-saving installation. The rectangular pieces come in three different lengths that fit tightly together, with unique face textures. On the back of the stone, a 1/4-in. groove creates a clean 1/2-in. gap when the stones are laid together, making it easy to fill and blend mortar, and forming virtually seamless lines between the pieces.
