CMU Basics | Configurations

Solid units used as Components are ideal for structural applications greater than 12 inches in width. The basic configurations shown below are common to hollow blocks in various sizes.

	Standard Full face shells and webs.		Open End Standard Open one end only. Used for OSA work, solid grout, and continuous reinforcement.
