[GreenKeys] Why the "Can" in Can Wrench

[Steve Schlink]

If anyone is still interested or curious what on "old" 216B can wrench with 
the spring load feature and screwdriver looks like, here are a few photos.

And while the 216 wrench has probably only been used for protector blocks 
for the last 50+ years, I still maintain that the moniker "can" derives 
from its original use on pole mounted 30-type terminals circa 1900. The 
cover for these was a 10"-12" metal cylinder with a cone top that slid 
straight up and off. Mine isn't handy for a photo at this time, though.

Take care,

Steve
