Window sash balances

Hello,

We can supply your replacement 3965 stamp balances to support a sash between 39-42 pounds but it will need to be a custom order since our stock options will not support your sash weight. Before we get started, we strongly encourage you to send us photos of your original balance removed from the window and confirm that the bottom fitting measures exactly 1-3/32" deep as shown below. We want to cover all of our bases since these balances will have a 5-6 week lead time and are non-refundable. Thank you!

Thank you for confirming. You should be good to go as long as the top fitting matches the 19-005 that comes attached to the Series 385 balances. We just sent over an order link and price quote for you to review. This does not include the 18-171 top sash guides but they can be added to the same order directly from our product page. Take a look and let us know if you need anything else.
