1820 channel balance

A quick learner from Amherst MA says:
I am returning the larger ones I purchased. I now found out that it is only 18". A neighbor where my house is took out the other one for me and found a marking on it. Do you have 18"? If not, I guess I could try the 19" and see if we can get them to work. Thanks.

Hi there!

I see you ordered the Series 385 . We do carry this channel balance in 18" and 19" which would be our S385-18 and S385-19 .
