I have a house built in 2002. All vinyl windows are contractor grade (likely from lowes) but have no identifying markings. Almost every one in my home is broken due to the brittle plastic parts at this point, and need to be replaced. Do you have something that will work? Please see the photos attached. Thank you!

Hello! This is the old crossbow balance. This hasn't been made in many years now, but the good news is that our Series 795 can be used as a substitute. Just check the diameter of the spring to ensure that it's 1/2". If it's smaller, then let me know and I can suggest something else. Otherwise, you're good to go.

I also recommend watching the video below. The process of using our balance as a substitute is a little involved but this video walks you through it step by step.

Thank you - I saw this adaptation after sending the original email. Are they available as a bulk purchase/price, as I will need about 20 of them. It is a 1/2" spring - and i also thought the video said to measure the black part with the locking cam - will that make a difference in the substitute's part number as well?

We do have bulk quantity discounts, yes. You can see a detailed price breakdown on each store page for the respective lengths of the Series 795.
