This ISO-KOP Electrical Isolation Knockout Panel from Middle Atlantic is a special knockout panel designed to work with electrical installations that require the electrical conduit to be isolated from the enclosure. It is designed for use with MRK, WRK, DRK, ERK, SCRK, and ISRK series enclosures. It will also work in the bottom of 60° SC and SCQ series consoles. If so desired this panel can be used to replace the standard rear electrical knockout plate in these enclosures. It is constructed of 1/8" thick non-conductive Lexan. Assembly hardware is included.
