The Keystone Mini 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" (200 mm) high Standard or Compac units. The unit is also used for the 4" (100 mm) high cap module to complete most wall installations. The cap unit has a smooth top surface without openings to give a coping appearance.
