These Masonry Boxes are designed to provide the strength and flexibility you need to install power and data options into masonry. These durable 2.5" to 3.5" deep electrical boxes are available up to 10 gangs, in both solid and gangable styles. Solid boxes speed up installation times for jobs that won't require any future changes, and gangable boxes are ideal for applications that may change unexpectedly in the field.
