Clip to hold window balance

Question

This clip screws on to the top of the window balance and keeps the balance moving with the window when the window goes down.

This is on an aluminum, non-tilt window.

I would appreciate any help in identifying it and getting one.

Thanx...john

Please see our 18-009 top sash guide. This looks a lot like yours, but compare our measurements to yours to confirm.
