Betts offers an extensive line of Full Opening Manholes and Fills to meet a wide variety of applications.

A representative part numbering system is used for the full opening manhole line.  Each letter or digit in the part number is indicative of a feature or option as shown on the chart.  If an option is not covered by the standard numbering system, a three-digit suffix will apply.  All options and part number combinations may not be listed, available or even possible.  See individual product catalog pages or contact a Betts representative for assistance.
