Parts Desk Insights
Best use case: Automating shore power cable handling on a boat with a 50A connection, so the crew can extend or retract the cable at the flip of a switch instead of coiling it by hand.
Most common customer mistake: Not checking the cable size and storage space before ordering. The CM7 handles cable from .83" to 1.14" outside diameter, and how much cable the system can hold depends entirely on the size of the below-deck storage area, so measure both before ordering.
Sizing and fitment guidance: Confirm the shore power cable's outside diameter falls within the .83" to 1.14" range, check that the 12V system can power the unit, and measure the space for the storage container. The unit measures L 18" x W 6.3" x H 12.5", so plan the installation footprint and deck routing accordingly.
