Overview

The Garmin 010-11170-01 is a split connector collar for 11 mm Garmin cables that lets you route wiring through a smaller pass-through instead of drilling a large hole to fit the plug.

It is used on Garmin installations that rely on a threaded locking collar connection, including threaded RJ45-style network leads and other Garmin cables that secure with threads at the device end. Because the collar is split, you can pull the cable first and assemble the collar afterward, which is helpful on refits and tight helm layouts.

Confirm fit by checking that your cable jacket measures about 11 mm where the collar will sit and that the mating connection uses a threaded lock. If the connector is a friction-fit style with no threads, this collar will not attach.

Key features

• 11 mm split collar format to keep cable pass-through holes smaller
• Threaded locking collar style for Garmin connections that secure with threads
• Split construction allows assembly after the cable has been routed
• Useful replacement when the original collar is missing, cracked, or stripped
• Black finish that blends in behind the dash and inside conduits

Compatibility and fit

Fit depends on two things: cable outside diameter and the connector locking style. This part matches Garmin cables that use an 11 mm collar and a threaded lock at the connection point. It is not meant for friction-fit connectors that do not have a threaded port to screw onto.

On mixed electronics systems, it is worth checking each cable run individually. Some boats have a combination of threaded and non-threaded Garmin leads depending on the device generation and cable type.

Installation and setup

Route the cable through the bulkhead, panel, or rigging tube first, then assemble the split collar around the cable jacket. Once assembled, thread the collar onto the matching threaded connection and hand-tighten until it seats.

For installations exposed to washdowns or spray, treat the pass-through like any other deck or bulkhead penetration: seal the cutout appropriately and add strain relief so vibration and cable weight are not carried by the connector.

Use cases on board

This collar is commonly used when running Garmin network or transducer cabling behind the helm, through console rigging, or across a bulkhead where you want to keep hole sizes down. It is a good match for boats with limited access behind the panel where pulling a large connector through the structure would be difficult.
