Measuring only 68mm x 40mm the FBA-1 will fit most floor boxes. The adapter converts
the HD15, VGA connector into 5 electrically isolated 75 ohm BNC sockets spaced for
easy connection. The maintaining of independent ground for the three video channels
and the syncs ensures that the adapter does not degrade the signal.
For use with heavier cables the FBA-1B incorporates additional support brackets.
