Hello,I have sliding window that is 18 lbs, the balance sliders ID number is 13-5 JN5 CMC 8, the channel length is 14 inches, according to your chart the sliders I have are inadequate to support my window.I am hoping you can recommend the proper balance slider for me.let me know if you need more details or where to send photos. Not sure if you noticed the springs in the photos, there are 2 different sizes, the smaller spring is very tight and the string on that one has broken. The one with the larger spring has a string which still intact, that spring has more stretch to it. Do you know which would be the best spring for my application?Thank youWayne

Hi there Wayne.
Thank you for reaching out to us. We can help with this. It must be a custom order, however, due to the blue washer that connects the spring and pulley together. Can you confirm the number of balances you'd like to order? Can you also measure the bottom shoe as shown below and tell us what you get for the depth? We can draft a price quote once we have those details.
