The Keystone Mini Unit is a great solution for smaller, non-critical applications. It is easy to handle and easy to install. Makes for an attractive wall on its own or as an accent when integrated with the 8" (200mm) high Standard or Compac units. The proportion and scale of the Mini units blend well with brick and ledge stone typically found in residential construction. the unit is also used for the 4" (100mm) high cap module to complete most wall installations. The cap unit has a smooth top surface without openings to give a coping appearance.
