Thanks for posting! I think the key number here is "7 27." Is that "4" printed differently, perhaps smaller or in another font? If so, see our 24-737. This can replace Andersen balance boxes marked with "7 27."
A quick learner says:
After looking at the number again it looks like the 4 is a # sign, si it would be 7#27

Great, the 24-737 sounds like a good replacement then.
