Need 2 sets of channel balances and 4 sash guides

Thanks for reaching out to us, Bobby! Before I make my recommendation for the balance, can you show us a photo of the inside of the metal channel where the innerspring connects to the pulley mechanism?

As for the top sash guide, our 18-009 comes to mind. Have a look and see how the specifications compare with yours.

Thanks for getting back to me, Bobby! Based on the information you've given, I recommend the S385-30 channel balance with the 2940 stamp option if your window has been working this whole time without issue. A pair of balances with the 2940 stamp can support a sash weighing 23 to 28 pounds. 

However, we also have the 2950 stamp. A pair of balances with this stamp will support a sash weighing 28 to 32 pounds. The decision is ultimately up to you!

Thank you for your order! We truly appreciate it. Good luck with the repair; I'll be here if you need anything else!
