Description

The EH-MKIT marine kit is designed to work with light-to-medium enclosures compatible with EM1512 and EM1450 wall mounts. The EH-MKIT marine kit protects the enclosures and the wall mounts from galvanic corrosion by electrically isolating the system from the mounting structure. When installed correctly, the marine kit eliminates the conductive path between the aluminum mount and the dissimilar metal of the mounting structure.

The EH-MKIT marine kit includes the following parts:
