An ultra modern contemporary feel, defined by clean lines, varying depth and symmetrical cut stones. A modern twist on an American Classic combined with a panelized system for fast efficient installation using mortar. Apex is characterized by a rich gray, hints of brown and accents of gold and burgundy.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.
