The Keystone Standard is an American original. What started the industry is still the industry leader. Its height-to-depth ratio delivers a structurally sound, engineered wall system with superior construction stability, durability, and strength. The choice for tall walls and critical structures.

The Keystone Compac is the perfect choice where the deep embedment length of the Standard unit is not required. An installer's favorite, its lighter weight and shorter tail design makes it easy to handle for smaller walls.

Exposed Face Area: ½ sq. ft. - 4" x 18"

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 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" (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.
