Which Balance do I need?

I think I found the right balance, but not sure. There are no numbers on mine, but I found a photo that I think matches. Seems to be the S351-23 24" Series 351 Channel Guide. Help!

I'm afraid I cannot determine what you need based on these pictures. The only way to know if our S351-23 will work for you is to carefully compare our specs to your own hardware. Are the nylon attachments the same? How do the dimensions line up? What is the weight of your sash? Based on the S351-23 chart, can any of those options cover that weight? Check out the S351-23 store page, where we have detailed images and videos of how this hardware works.
