window channel

A landlord from los angeles says:
I think I located my window channel balance as Series 350 (It is 22 inches long and the number on the surface is 21100).

The top sash guide should be 18 - 172

Here are the pic. Pls help.

I need several

Thanks for posting, Alberto! I do believe that you have an S350-22 channel balance. I would choose the 2110 stamp option with that.

As for the top sash guide, it does look similar to your 18-172. Please compare their dimensions and see what you think. Keep in mind that the most vital dimensions are the width, depth, and height. Let us know what you think.

Tks for answering.

The top sash dimensions is matching 18 - 172.

There is nothing closer than 18 - 172. Do you see any better sash to match mine than 18 - 172?

Tks

It certainly seems to be the closest match, especially if you say the dimensions are the same.
