In 2017, Keystone introduced lip/lug structural units to compliment the current Keystone unit offering. The units include the rear lipped Regal Stone Pro unit and the Broadstone and Valera units which have lug connections. These units are similar in size to Keystone Compac units and also accommodate geosynthetic soil reinforcement.
