5/8 Top Sash Guide

A quick learner from Florida says:
I have some 22 year old windows which use the Series 351 channel balancers....which I have ordered. The top sash guide is similar to the Model 18-009. The differences are:

1: The 19/32 dimension is 7/16. (right pic)
2: The "not shown" dimension below is 5/16. (right pic)
3: The 11/16 dimension is 1/2. (right pic)
4: The 1 11/32 dimension is 1 1/2. (right pic) I think this will work ok.
5: In pic 2 the thickness and holes are correct.

The windows have no markings at all...or are long gone!

So it's basically too thick. All the others sashes seem to have something else wrong. Any ideas?

Thanks for posting! If the holes and width are the same, then it may work for you, but I can't know for sure without seeing a few pictures. Sometimes there are subtle differences in molding and design that can only be noticed by seeing the actual product. Let me know if you can get me a few pictures!

Great pictures! Thanks for the additional information. Have you seen our 18-166? Could this be a possible replacement for you?

This is exactly the part I need. Don't know how I missed it. Must have been because it was near the bottom of the sash page. I have ordered 50 for a few spares.
