Type C manhole frame and covers are the same as a type A with webs added. In the past, webs were added for additional strength or to improve concrete installation. Today, with modern concrete materials they are no longer required. Available with any type of cover design required. Exceeds H-20 and HS-20 load requirements.
Please Note: Our 2006 Catalog makes slight changes to our traditional Catalog Number and Part Number systems. We have added a three digit suffix to provide a unique set description on Catalog items where we formerly had a maximum of one - i.e. an LC324-100 becomes an LC324-1-000.
