I prefer Schlage padlocks because I can key them to my house key.
Because they have lock cylinders that will open in less than three seconds when raked. About the only thing that makes the difficult is that the things are so horrendously machined that you have to put more force on the core while doing so (might bend thinner tension wrenches).How so?
Some of the better ABUS locks can take a Schlage core. Adding a few spool pins will show things down a bit.I prefer Schlage padlocks because I can key them to my house key..
