• how to handle an anode-cap
1
Don't hurt the surface of anode-caps with shaped
objects!
2
Don't press the rubber too hard so as not to hurt inside of
anode-caps!
A metal fitting called the shatter-hook terminal is built into
the rebber.
3
Don't turn the foot of rubber over too hard!
The shatter-hook terminal will stick out of damage the
rubber.
