balance replacement for vision 2000 window

Thanks for posting. I am afraid I don't believe the standard Series 751 balances will work for your window. The standard Series 751 uses our 15-014 Knife Lock Shoe; yours appears to be different in shape, and that color designates a different grade as well. If you already procured the Series 751, you can view our return policy here. I will shortly send you an email with a custom link to order (4) 34" Series 751 balances, stamped 33TG, and with these custom Knife-Lock Shoes attached. Let me know if you have any questions prior to ordering, and do confirm this is the length and stamp code you need before proceeding.
