Keystone Compac III®

The No. 1 commercial retaining wall product on the market, the Keystone Compac III® unit is an installer’s favorite.

Featuring an open-core design and a pin connection system that is trusted by engineers and contractors around the world, the Keystone Compac is lighter weight than the original Compac I block. It has a shortened tail design that makes it easier to handle and is perfect for projects that do not require the embedment length of the Keystone Standard unit. Compac units are PennDOT Bulletin 15 and MDOT approved.
