The Series 730 is not recommended, it is normally used in windows manufactured by Silverline.
Alenco commonly uses a combination of 15-001
. The photo of the balance shoe is not good enough for us to determine if the 15-001 is the needed base fitting, just compare the original balance attachments to the measures shown on our site for these attachments before placing an order.
If you do determine that your balance attachments are our 15-001 and 19-005 you will need to order our S395-28
Let me know if you have any further questions.
