872 yale

[nathanbonstein]

i think they changed to the pin holding the plug in very late 60's early 70's. After they removed the lubricate with graphite words in the late 60's.
Maybe Pete or BBE would know,i'm just guessing. If you or anyone else knows where i could purchase 4-6 of the 870 plugs ,with the older screw retainer
i am interested or trade i have new plugs with ge keyway for the screw retainer 850,840 yales. i think they both use the same plug ? As long as the keyway is not to restricted so i can get blanks for them.

Unfortunately I don't have any extra plugs for these. You might find some on eBay, not too long ago a seller there had a bunch of them listed, not sure if they fit all the different 8xx locks though.

plug info--it could be the 6 or 7 pin, maybe someday. Think i'll just make up a longer driver,that should work

restricted keyway,so i milled down a different restricted key ,both grooves and narrowed the lip . all three keyed same bitting.

should not have to take another apart, unless there is a problem,like the first one.

When you say restricted, was it one of the G, S or T family multiplex sections or something different? Please see thumbnail attached.

thank you ,Pete, i even tryed 2 times on the gst and just wasn't enough meat. they kinda came apart. i did make the driver up and it works.
still have not figured out how they got these padlock 9/16 shackles in and with the same keeper as the 870's.
