Keystone
Compac® Tri-Plane

Compac Tri-Plane

The Keystone Compac's traditional sculptured tri-plane face adds visual appeal to any project through its use of depth and shadow.

Its lighter weight and shorter tail design make it easy to handle for installers and a perfect choice for projects that are larger retaining wall applications.

The improved geometry of the Keystone Compac Unit allows for easier installation and increased connection strength with geogrid reinforcement.

Also Available: Compac® Regency | Compac® Straight Split
