    Simple and Effective

    Posted by Isabella on Sep 7th 2023

    The Don-Jo AST-21342 from Zensupply is a no-frills strike plate that gets the job done. I like its sturdiness and easy installation. However, it lacks fancy finishes, so it's not the most stylish option. But if you're after security, it's a winner.
