We recently received a question about Unistrut Post Base tension loads from one of our clients and decided to share the response with our loyal Tech Talk readers.
Two of the most popular post bases in the Unistrut catalog are P2072A and P2072A-SQ. If you want to learn more about the differences between these fittings, we suggest checking out our recent Tech Talk article on Unistrut Post Bases. Now let’s take a look at the load data, starting with the P2072A:
