A rugged stack stone that incorporates a panelized system for fast efficient installation using mortar. Rugged yet refined, a touch of the wilderness with a touch of class. Foggy Mt. is rich with light and dark grays, soft browns, with hints of burgundy and gold accents.A sister product to our MSI Stones that simply lack the rail system on the back, the Superior Fit utilized the panelized system but is installed with mortar. The combination of the panelized system with the mortar installation makes this product ideal for block, brick and any project that would call for a mortar based installation.
