The ZB4/XB4 series have metal operators and mounting collars.  The ZB5/XB5 has plastic operators and mounting collars.

Both lines use the same contact blocks, light modules and accessories.  Just the collars and heads are different.  The mounting collar for the metal line is ZB4BZ009 and ZB5AZ009 for the plastic collar.  The operators and collars are not interchangeable between plastic and metal.
