Hi Dan

If I understand properly, how would a metal "SO" connector be bonded in 
a plastic junction box useing USE-2? For us a metal connector is only 
used with a metal box. The metal nut on a plastic connector would need a 
bonding lug on it when used with a plastic box. Metal lock nuts with 
bonding lugs exist if you realy want to use them.
