Balance

Thanks for posting. I'm sure we can replace these spiral balances for you and the pivot shoes, but we'll need a little more information. First off, you'll need to confirm the diameter of the metal tubes. It should be either 3/8" or 5/8'. If it's 3/8", you have the Series 900. If  it's 5/8", you're looking for the Series 600. Based on the color of the 37" balance, I suspect you're working with the Series 900, since the S900-37 has either white or yellow options, but it doesn't hurt to confirm to be safe. 

You then have to choose a color tip option, which determines the strength of the balance. Assuming you do have the S900-37, that color might be yellow; but it could just as easily be an off-white. The best thing to do would be to obtain the exact weight of the window sash. Once you have that exact weight, you'll know whether or not you need a yellow or white tip option. The white tip will support a window sash in the weight range of 7 through 22 pounds, while the yellow will support 24 through 34 pounds. 

For your 25" balance, it's a bit more straightforward--that's just a faded red tip, and that's the color to choose once whether it's a S600-25 or S900-25.

Finally, for the pivot shoes--there's actually loads of different pivot shoes that work with these balances. The best thing to do is to remove an undamaged one and show us a clear picture, and also provide us its width and thickness. That should help narrow down your options. The video below shows how to remove and replace pivot shoes used with spiral balances. Let me know if you have further questions.  

Sure thing! I'm happy to advise on the shoe whenever you can get that for me.

If you're at all unsure of which color tip to pick, I highly recommend weighing your sash on a scale so that you can 100% verify. Trust me, it's better to check that before you buy anything.

Great! I see you placed your order, and I agree with the parts you picked out.

Thank you very much for the business and please feel free to reach out if you had any other questions.

That is very similar in design to our 38-036. You can review its specs below to determine if you think it's worth giving a shot.

While this balance has a white nylon cover, it's actually the same kind of design as what you were looking for before. Therefore your options are the same: either the 3/8" diameter Series 900 or the 9/16" diameter Series 600. The only difference is that our tubes are metal, not nylon, but that doesn't matter at the end of the day. They'll work the same.

Your next step is to measure the diameter of the white tube to determine whether it's 3/8" or 9/16". Those are the only two options, so it has to be one of those.
