A locked door alone won’t always keep intruders out, but adding a 2x4 hanger bracket set reinforces your security with ease. Made from 3.5mm thick, rust-proof iron, it withstands up to 700 lbs of force, providing a reliable physical barrier that won’t fail like alarms can. Quick to install with minimal drilling, this simple yet effective solution works for homes, barns, sheds, and more.
