This is a "Concept Plus 10-Pin High Security" lock...picked up from eBay for about 10 bucks including shipping....not a terribly hard lock to pick, just time consuming because of the two rows of pins that are offset, so the pins lock up really quick if you don't use feather weight tension. Also the bitting was a bit of a bitch with a low high low in the first three pins. Anywho...thanks for watching. Check out
