Review on Master Lock 410BLU Lockout Tagout Safety Padlock With Key by Randy Perry

Definitely not for actual implementation of OSHA safety regulations Disclaimer. If you want to replace the higher security core with a Master Lock 930DPF or similar model that has a weak and easily damaged 5-pin plug-in core, the 6-pin core is an easy replacement, with the only downside being that you have to essentially destroying injection molded plastic. But in return you get the most reliable and affordable padlock that Master Lock SHOULD make but isn't designed to do. For some reason. Seriously, Master Lock, up your security game and start putting those cores in more locks. I don't understand why this isn't STANDARD for your high security locks.
