Hey all. So I am going to install a LiveScope transducer to a pole mount I made. I need to drill a hole in the gunwale to run the cable how I want it. My question is, what is the piece called I would want to put over the hole I drill to round the edges and protect the cable? A bushing? Grommet?

Second question, there is a hole drilled already where the precious graph wiring went through. This hole has a screwed down cable router/protector already there but I may need to make the hole bigger for the new wires. I just can’t for the life of me find what these things are called or a good site to buy them from.


Thanks sorry for the long post.
