CIRCULAR BACKSHELLS




               Modification Codes
               TE’s standard range of backshells can be extensively modified using the
               codes listed below. Many of these options can be used in combination to
               create a solution to suit most needs. Consult TE Engineering for correct use of
               modification codes.
