If you want spools you can get the 410LOTO version. American case with a 410LOTO core, get 5 spools and 1 serrated. If you have any original Mater 410LOTO's that you rattle clubed trying to do a 360 you can get them out of there too.

Here is a listing on Amazon. The crazy thing is it is only like a dollar more expensive than a Master 410. I really don't understand why they aren't more popular. I mean $10.66 for a plastic lock that is dead if I turn the core too far VS $11.50 for an aluminum lock with the same core that I can gut for repairs or repinning. Seems like a no-brainer to me.
