Item À Á Â Ã Description Chartplotter GCV 20 Power Source Transducer Cable Routing Grommets When routing cables through your boat, it may be necessary to drill holes to route the cables. Cable routing grommets can be used to cover cable installation holes. The grommets do not create a waterproof seal. If necessary, apply a marine sealant after installation to weatherproof around the grommet and the cable. You can purchase grommets from your Garmin dealer or directly from Garmin at www.garmin.com.
