What to use where battery wire exits frame?

[Samckitt]

I am running the battery wire through a plastic corrugated tubing in the frame & wonder what I need to use where the wire exits the frame.
Thanks

You would need at least a big grommet or thick rubber around the edge just to protect it from chaffing. If you can get to where you are passing it through, I'd use a battery bulkhead connector just to be safe, but being in a frame and most likely not near the end, that probably isn't an option.

I thought of the bulkhead & I have a couple of them, but not sure I can get to it, I'll have to try that.
