Purchase 4 coils for weight balancing system (window sash)

Question

Weight of the window sash: ~ 22 lb
Height of the window sash ~ 89cm

My window uses Dual Coil balance parts as shown in the picture. Each sash uses 2 parts (one on the right side and one on the left)

coil diameter (when mounted) ~ 28 mm
Spring thickness: ~ 0.21 mm
Spring band width: ~ 12.5 mm

The coil end (screw location) looks like your model Series 190

I need 4 coils.
Please rash me info on the price, the shipping (3 day UPS), and how to order. This is urgent
Thank you

Thank you for posting. The shoe looks a lot like our 15-180. Carefully compare it to your own hardware and see if you agree. If so, then I agree that our Series 190 is the best match, since the Series 190 and 15-180 shoe go together.
