The Advantages of the Classic System . . .

It’s Fast...
Located on the underside of each Classic® block, the 4" x 2" Anchor Bar creates an automatic setback with the highest shear resistance in the industry. Plus, Classic’s fewer pieces, pinless design, and lower weight per square foot reduces construction time, labor costs, and freight charges.

It’s Simple...
“One Unit” construction is a vital element of Classic’s superior design. 90° corners and half blocks are made simply by removing a portion of the block. No special blocks are required; no special inventories are needed; no shortages occur on the jobsite!

It’s Strong...
Upon assembly, Classic blocks automatically create 4" x 5" vertical “stone columns”. When layered with grid, the gravel filled “stone columns” provide a multi-point interlock, for a more uniform block-to-grid connection.

It’s Versatile...
Variable setbacks, sharp radius turns, “One Unit” construction, and complete interchangeability are all features of Rockwood’s Classic System. The ability to mix various sizes and colors within a wall enhances your imagination without sacrificing structural integrity. Plus, the Anchor Bar allows you to build at any setback you desire – from 0° to 14°, providing the only “true” vertical setback in the industry.
