We are looking to create some Compression Molded Fiberglass reinforced polyester composite burial cases for low voltage transformers and lighting fixtures. The case will have a removable lid (14 screws holding lid) and 3 1 2" NPT conduit entries plugs and 2 3 4" NPT Conduit entries plugs. There is a silcone gasket between the lid and body of case to keep water out. I have an illustration I could send (PDF file) Thanks! Sean Perry Hevi Lite, Inc. (United States)
