The brackets will work only for the size of wood you buy to match the attachment areas. Simpson makes so many brackets but each fits a different purpose. Usually an engineer specs them out, but I have even contacted them for answeres to my questions, they where happy to help.

Good luck on your project, let us know what happens.
