Anti chafe on cables going in/out of radar arch?

[GHA]

Any tips?

There'll be a fair few, gps, radar, solar, antennas.. Coming out at the deck then down a couple of swan necks.
So how does everyone else do it?
Radar needed a big hole for the connecter and there will be a couple more sharing that hole.
So wondering, pipe lagging foam or maybe just a load of self amalgamating tape.

Any bright ideas?

Would something like this work? https://uk.rs-online.com/web/p/prod...d1&gclid=CNq2htPbwt0CFcoaGwodfJMHzA&gclsrc=ds

Obviously you won't need a 25m roll, and 16mm is a bit big, but it's the first link I found. As far as I'm aware it's quite normal to use it as anti chafe protection.

This is my radar arch with radar, wind generator and TV antenna mounted on the aft tube that is made in one piece down to the deck mounting.

The deck mounting has a hole right through the deck so no swan neck of special sealing needed

Ot the forward end is a trunking running all along the aft side with all my other antennas connected into the trunking with a 25 mm dia hole each side so wires can also pass down the forward legs direct to below deck

I have used short lengths of 40mm PVC tube to prevent chafe at the deck connection and 25mm PVC conduit where the wires pass through from the forward trunking into the down legs.

No chafe in the 10 years since fitting.

I use a few layers of heatshrink tubing.

It also helps to round off the edges of any holes that you drill into the stainless tubes.

Thinking of butchering some grommets for smaller holes and epoxying them around the hole so rubber all round.

This will do the job but and rubber panel edging will also do if you can get at it easily.

Quick test looks like it should work, hopefully I've enough big (but not quite big enough..) grommets in the stash to butcher then epoxy in, looks like it should be OK for the outside of the hole. Then when all the cables are in maybe wrap in some sort of rubber and self amalg tape to hold in place. Nice to get hidden though, been looking at those cables taped down the side of the arch for years Going straight through the deck with a hole under the foot of the arch has been a source of corrosion so everything welded no with studs, just a couple of necessary easier to get at holes for the cable going through the swan necks. Might work, thanks all
