Sash window channel balance and accessories.

Thanks for posting. Let me see if we can clarify what you need here. You show two different types of balances, one with wings on the top and bottom fittings (those side tabs), and one without the wings. The two balances have different stamp codes as well, which would leave me to believe they are not at all interchangeable with one another. 

Are they from a different window, or from the same one? If they are from different windows, did one of these windows not function well even before the balances break (e.g. was it difficult to open, or to close?). I may need more information from there, depending on the situation.

As far as the Top Sash Guide goes, I am afraid we don't have an exact match, but we believe our 18-009, 18-064, 18-166 or 18-188 might work as replacements. Look over each and see if you think one of these might match up. My bet would be the 18-009 or 18-166, but it will come down to the dimensions.
