Chafe protection for electric wire

[twhite]

Hi Brian,

I'm wondering what to use for chafe protection. Were going down to the boat next week, and I'll be mounting a radar and to GPS antennas to the mizzen. I want to run the wire inside. The radar is the largest of the cables, it requires a 1 inch hole to get that flat connector through. The GPS ones are much smaller. And each one has to have some sort of a strain relief at the top end.

On our smaller boat I was able to use a grommet for whatever I wanted to run up the mast. But this mast is going to be much thicker, and the grommets I have are made for relatively thin plate, probably 1/8 inch. I have some NEMA fittings, in the appropriate sizes, but they require either a nut behind them, or to be threaded. Threading would be difficult, since I would be leading them through a curved part of the mast. So I was thinking that there is something that you professionals use.

Best wishes, Tom
