    Waterproof cable fittings for sonar cable wiring?

    I'm looking for some cable bushings or gland nuts that I can use to wire a sonar installed on top or my center console. I'll need about a 1/2" or 3/4" hole to feed Lowrance power and transducer cable thru, and I don't want to cut and splice the cables - I want something big enough to pass the connectors thru without having to splice them. The sonar is mounted on a RAM ball on top of the console with double-sided 3M tape. I'd like the connectors routed there, with a few inches of slack, so I can disconnect and remove the sonar to prevent thievery.

    Was looking at these : https://www.electricalhub.com/sealco...f-dome-fitting , but I'd have to get one large enough to pass the connectors thru. It would be nice to find something that is split so you can put it around the cable prior to install. I'd like it water-tight so I can not have rain dripping inside my console. I could drill a hole, and use a standard grommet, but I'd have to goop it up with sealant to make it watertight.

    Ideas?

    One of these two fittings and sealed with silicone or putty after installation:

    Google Heyco split gland cord grips.
    If you have integrity, nothing else matters. If you don't have integrity,
    nothing else matters.​

    Thanks, Wayne, I did buy a 2-pack of those on ebay, the ones for $7.75. These will do the job, with a squirt of RTV in there to water-proof it, but I would still like something that I didn't need to screw down.

    EDIT: Thanks CatFan, I forgot about Heyco, I use their strain reliefs all the time building amplifiers.

    Perfect.
