Benefits
Clip-On Mounting
Designed for mounting to the upper front structure of an ISO container. Quick connection to upper container corner castings with steel pin clamps and ¼-turn latches.
Refrigeration-Unit Compatibility
Genset envelope considers access to control boxes on Thermo King, Carrier, StarCool, Daikin, and Klinge refrigeration units, for either standard or high-cube containers.
