Replacement Locking Collars for Garmin Marine Devices

Newer Garmin cables do not have the locking collars factory-installed; this allows for easier installation when routing the cables through and behind cabinetry. The two-piece locking collar is attached to the connector. Double-check, the box for the included split locking collar but if lost or if a replacement is needed, see the below list for part numbers. Refer to  Marine Cable Locking Collar / Split Connector Installation for instructions.
