Need Battery Box Cable Feedthru

[perryg114]

I lost one my my battery box cable feedthroughs and I was wondering if anyone had a source for them.

Are you referring to grommets? If so, most auto parts stores carry them. All you need is the hole diameter in the box and the size of the hole you want in the grommet.

I would call it a strain relief and seal. It is made of metal and has a nut and a rubber gromet inside that nut that is compressed to make a water proof seal. Mcmaster.com has them. I just need to match up the hole in the box to the wire diameter. Mcmaster-Carr calls them cord grips.

When I made our battery box, rather than passing the cables through the box I made insulated feed-throughs with a nut on each side. Below is a commercial version - I just turned some from chunk of Delrin on the lathe.

Yeah those bulkhead feedthroughs would work well. I think I will not try to reinvent the wheel and use the stock holes in the stock replacement battery boxes. I ended up putting the stock type battery boxes back in and they seem like they are better made than the original ones. I also plan to support them from the bottom to reduce stress on the plastic. I was thinking of a wedge of wood made to support the bottom of the box.

Me too, thanks to the folks here on the Forum. I had never heard of them before you all advised. Since then I have found LOTS of bits I can't find anywhere else.

Us engineers use McMaster-Carr all the time to buy stuff to build things with. Their prices are not the lowest but their service and fast shipping make up the difference especially when you just need small quanities of stuff.

Perry,
I'm really glad you brought up McMaster-Carr. I've seen their website before, but I had forgotten about them. I now have their website saved as a favorite!

Thanks again,

Steve
