28-1/2" spiral tube length

A home owner from Ohio says:
My tube diamenter is 3/8" and the tube length is 28-1/2" long, excluding the green tip. The internal spiral length is 29-3/8" long, top to bottom. What item should I specify? Also, what tool do I need to install?

Thanks

We could make a 28" x 3/8" spiral tilt balance with a 29-7/8" internal spiral for you.
Let us know if that could work for you.
SWISCO product code 75-006 is the needed charging tool.
A home owner from Ohio says:
I really don't know it that would work or not. The balance would be 1/2" shorter and the internal spiral would be 1/2" longer that the original ones. I'm afraid I am going to ask you the same question.

Sorry, but this is the only option I can come up with. I've researched several other ideas and this seems to be it.

Unfortunately, I can't be certain whether this will work with your application. I wish I had something more helpful to give you at this time.
A home owner from Ohio says:
Paul,
You suggested I consider a 28" x 3/8" spiral tilt balance with a 29-7/8" internal spiral, green tip?

How does this differ from the standard 28" balance?

Thanks

The 28" Series 900 has a spiral that is 28 1/2".
A home owner from Ohio says:
Would you see any problem if I simply lowered the balance (move the attching screw down) about one inch and used the standard 28" balance?

I don't see any problem with that at all. That is a very good suggestion.

Thanks for your help Paul, I will give it a try.
