The Keystone Mini Unit is a great solution for smaller, non-critical applications. Easy to handle and easy to install, the 4” Mini Unit makes for an attractive retaining wall on its own or can be used as an accent when integrated with the 8" (200mm) high Standard or Compac units. The proportion and scale of the Mini Unit blends well with brick and ledge stone typically found in residential construction. The unit can also used as a 4” high cap unit to finish most wall installations. When used in this manner, the smooth top surface of the Mini Unit provides a project with the finished appearance of coping.
