About the MEIA™-875 Interface

A modified EIA interface design that replaces the standard flange mount configuration with a light weight, threaded coupling that makes installation easier, reduces overall outer diameter space requirements and retains the inner line size and power handling capability of the standard EIA interface. Standard sizes corresponding to EIA standards include the MEIA-1625 (EIA 1-5/8) and MEIA-875 (EIA 7/8).
