850 crossbow balance

A quick learner from Minnesota says:
I have the 850 balance in 22.5" but the shoe is blue and appears it would be 1" wide estimating for the missing broken piece. Is the white 1" wide shoe also 7/16" deep? and would it work?
Thank You

Thank you for your patience in this matter. I haven't been able to find this kind of balance with a Blue color shoe. It may be something unique to your window. That said, can you give me the weight of the window sash? In this instance, I think that would be the better gauge of what can work.

I weighed the sash, it's 15 pounds. I hope this helps.

Perfect, thank you. I recommend the Black shoe, since that is meant for sashes that weigh 6 through 17 pounds. Just measure the width of the shoe to determine which size Black shoe you need.
