Coil Balance for Vinyl Window

Thanks for posting. I am afraid I'm not familiar with this coil balance assembly at first glance. We need to see the pivot shoe that the coil springs attach to. The pivot shoe should be further down the window track. It's the plastic block to which the coil springs connect to, and from which the window sash pivots from. The identity of the pivot shoe typically tells us the identity of the coil balances needed. If you can send us some clear pictures of the shoe, preferably removed from the window, we'll do our best to assist you. 

There's really no getting around removing these assemblies from the window for replacement and maintenance, I'm afraid. The video below goes into detail about how to do this. Take a look for guidance. 

Hey Fadil. This pivot shoe looks like an older version that was discontinued not too long ago, but our 15-177 likely can replace it. The 15-177 works with Series 152 Coil Balances. Both the old shoe and the 15-177 absolutely do connect to the coil springs; the tape runs along the side of the window track to connect to the shoe. The coil springs and the shoes must connect, or else quite simply there's no way the coil springs can help regulate the window movement. I'd remove the shoes and springs to confirm the 15-177's width and thickness matches your old shoe (see the diagram below).

You'll then need to compare to remove the old springs and look for stamps on them that designate their spring strength--each individual spring is calibrated to support a specific weight. If there is no spring or you are uncertain, give me the exact weight of the window sash and I can work out the spring weights you need.

Hello, Fadil. The sash will stay in the frame without pivot shoes, yes, it just cannot be opened or else it will immediately fall. That is the major risk: if someone doesn't know the window doesn't have balance support, then they will risk injury if the sash were to then fall on their hands. If you do put the sash back in then I recommend keeping it locked and making sure everybody in your residence knows that it shouldn't be opened until repaired.

Otherwise, the tilt latches at the top two corners of the sash will keep it from tipping forward. As long as it remains closed it should be just fine.

You're very welcome! I was happy to help, of course. Please feel free to reach out if you had any other questions.

Unfortunately, these coil balance parts are not available as a complete unit but it does look like the 15-177 would be our closest replacement option, as well as the other parts shown under the related items section of our product page. One difference that I noticed is that your cam in the center of the shoe is enclosed and plastic, while ours is open and metal. I would recommend showing us a picture of the pivot bar that engages with your pivot shoe cam uninstalled to determine if it would be compatible with our replacement. We've related a few more videos on this page to assist you. 

Hey Fadil. Sorry to hear you had to go to all that trouble! Glad you at least have it sorted. If you ever have any other replacement hardware questions, feel free to reach out again.
