    I have a few places I need to run a wire thru a composite glass panel. I.e. propane solenoid wire, etc

    Is there a standard composite bushing for this type of thing so the wire isn't abraded by the glass on the core?

    Something like a nylon bush would suit ? But how to stop it falling out, a tight fit might stay in place.

    I've always bundled my wiring into a PVC conduit. If you have some light wires why not simply drill out your core, cover the wires with shrink wrap where they pass through and secure the wire with silicone caulk. I've done this with wiring up to "OO" gauge where the bulkhead was too thick for a terminal feed through connector. You're going to support the wiring, the silicone keeps it from moving and the shrink wrap adds additional protection.

    A nylon or PVC fitting from Home Depot would work as well. Just silicone it in. You're not pulling on the wire you just want to keep it from chafing.

    You mean heat shrink?

    Yeah, heat shrink.

    Try West Marine Catalogue. We use to buy this zinc thru hull flange bushing. There are many types. Other boat suppliers also carry this.

    I used a piece of rubber tubing and a dab of gorilla glue to secure it.

    Doesn't anyone use Duct Seal anymore? You can get it at any home improvement store. You just run the wire through the hole and then press the Duct Seal around it.

    I have it, but it hardly seems like chafe protection from fiberglass.

    When I ran some long battery cables to the generator, I passed them thru a 3/4 plywood bulkhead. Same concern about the insulation. I had some foam pipe insulation, the gray foam kind which is stiffer not soft black type. I over drilled the holes and slid in a 1 foot section, then passed the wire through that. So far it has been fine. I left it unsplit open. It has never moved out of the hole. The roughness of the wood hole and friction keeps it from moving. Staying in fine with no glue or tape. You dont want the black soft rubber foam, more expensive and the wire wont slide well on it.

    I am now using cut neoprene with cloth in it. Working fine. You can side slice it and slide it over existing wires as well. Screwing them on with some #4 or 6 wood screws ss.
