Window balance and top sash guide replacement

Hi there. I am confident we can help you find the replacements you need. For your top sash guide, have a look and see if our 18-009 is a good fit. As for your balance, we need to see a photo showing the nylon fitting at the opposite end of the balance. The nylon fittings on both sides are key components in recommending the right replacement. 

Thank you for replying back with photos. Have a look at our S380-35 channel balance. This comes with a 19-005 balance top and 15-005 bottom balance shoe. Compare your nylon fittings to ours to confirm whether or not this balance is a match. Since your stamping does not correspond with any of ours, you will need to weigh your sash on a scale and refer to the sash weight on the store page.
