The model RG15 mounts to properly equipped ISO containers, in front of the refrigeration unit's upper face. Generator sets are typically provided with "pin” mounting to attach to the container’s header rail. Clamp mounting to the corner casting of the container is available as an option. In either case, when mounted, the RG15 envelope allows access to the refrigeration unit control box. Additionally the design of the equipment considered a deep footprint to avoid tipping due to rough handling by yard forklifts, and fork pockets are extended and reinforced to eliminate fork tine damage.
