Keystone's patented pin system features high strength, pultruded fiberglass pins that provide a shear connector, geogrid proof positive holder, and alignment device all in one piece. Keystone's patented pin system ensures a positive mechanical connection between structural wall units and geogrids. The pins are the critical difference where Keystone provides the safety and security of a positive mechanical connection between units and geogrids.

CAPPING OPTIONS

A Keystone Retaining Wall is not complete without the "capping touch." Caps are available in 4" and 8" (100 and 200 mm) high units with choices of face styles and the option of angled or straight sides. ( Availability of cap options varies by region. Please call us to consult.)

Angled sides work great with convex curves.

Straight sides give straight walls a continuous coping without gaps.
