Some of my windows will no longer stay up by themselves. When I took the window apart these were the parts. I also have 2 window that the top drops down and will not stay up where they belong.

Hello,

We'd be happy to help but, unfortunately, your balance and pivot bar are too damaged to identify. If you could remove the hardware from a function window that uses the same parts, we'd be happy to look into this for you.

If the vinyl strips shown in your photo were used to cover the balance hardware, we won't be able to replace them but a local hardware store may be able to help. Thank you.

Is there a way I can still get these balancers for my windows? They are 24". I believe these are the pictures that you need to see. Thank you for your help Angie Long

Thank you for sending over the additional photos. This old arrow balance isn't made anymore but it can be replaced by our Series 770. If your balance is 24" long, see our S770-24. To know what stamp option to pick, you will need to weigh your window sash, then match that exact weight with one of the weight ranges listed for each stamp option on the product page. Take a look and thanks for posting!
