Bob,
You recently helped me identify a great pair of S385-22 (option 2140) replacements for my upstairs window.
The improvement was so great that now I'm doing the downstairs (single hung, side loading) window as well but it's a different size. The stamp on the existing balance is "33 6 AT CALDWELL". Measured length is 34" long. The bottom shoe is about 1" x 1 1/8".

Which balances will work best for this window? Thank you!

Hey there, welcome back! Glad I was able to help you; let's see what I can do for you now. You don't show a picture of the top nylon fitting. Does it resemble our 19-005, including the 'wings' on the side? If it differs at all, please send a photo. If the top fitting does resemble the 19-005, the bottom shoe looks like it's greater than 1", in which case I think you'd again need a Series 385. In this case, the S385-34, with a stamp option of 3360. But if you're uncertain of that top nylon fitting, feel free to send a picture. Many thanks again!

Bob,
Thanks for the assist - I wasn't sure what sides of the balance top and bottom needed to be measured. I think the 19-005 is what I need for the top fitting - it looks identical and the measurements are the same as what you show on your pictures.
The bottom is 1 3/32 so I've ordered the S385-34 with 3360 stamp as per your recommendation. Looking forward to having both of my windows working well here shortly!
