Not   just  a  coupling,   more   a
fuse for  your  motor.   It breaks
before  the  shaft  does.
    Don't
destroy your motor.  The motor
is worth more  than  acoupling.

There   are   few   who  can  say
"Our coupling will break." Don't
let   your   motor   get    broken.

Don't   run  unnecessary   risks.
Break     rather      than     repair.
