a look at the "big three" versions of Schlage Deadbolts B160 B360 & the current B60 and the differences in them.
*note, if anyone has the exact dates on mfg for each of these models, I would be glad to update it in the description here. In the video I was really rough on dates and just going on "offhand memory" which...my memory kinda sucks 😂
My best guess on dates is b160 era was predominant from about mid 70's to late 90's then came the b360 late 90's through about 2009ish. Originally the b60 was a "trade only available deadbolt" while stores and warehouses emptied their stock of b360's at box stores and then they integrated the b60 line. The cylinder change happened early 2016.
