1/8″ steel…. Is it strong enough with the M1-LT mailbox?

All fort knox mailboxes except for the M1-LT mailbox are 1/4″ steel. We believe 1/4″ steel is the way to go to defend your mail. Sometimes that isn’t needed in certain situations. 1/8″ steel is still thicker than anything you can get at a hardware store. With the design of the mailbox, it will certainly keep your mail safe from most attempts of break-ins.
