Spiral balances for Nuprime aluminum windows

Thank you for posting. Yes, I would be more than happy to help you identify what spiral balances you need!

First, can you tell me if your window is tilt, or non-tilt? Then, I will need to know the diameter and length of the tube itself. Finally, and if at all possible, I will need to know the weight of your sash in order to determine the appropriate tip color.

Please let me know as soon as you can, and we can work from there!

Thanks for posting. I'm sorry, but how many balances are you looking to replace? In order to recommend a balance for each window, I would have to know specific details about each balance pair that you have, including exact sash weights, tube lengths, and tube diameters.

Alternatively, you can look through the options available for our Series 600 spiral balances and see if you can select the ones you think you may need yourself. Otherwise, I'll need you to get that information for me!

To be honest, a red tipped balance supporting a 60 lb. sash doesn't seem right. That's a very heavy sash, and red tips are usually for somewhat lower weights, depending on the tube length. I highly recommend that you confirm the exact weight of each window sash, as well as the length and diameter of each spiral balance.

As for the handle, please take a look at our 40-049 complete mortise lockset. Do you think that may work for you?

There really isn't any table of colors and weight ranges. There are far too many different variables, and it would be too much to represent. The best thing to do is to let us know what the weight of your sashes are, then give us the Series and length of your spiral balance. With those three pieces of information, we can tell you what color tip you will need. For more information, please take a look at this guide:

Thank you for your patience in this matter. First, the pivot shoe looks somewhat like our 15-048. Please compare dimensions and let me know what you think.

Now, for the balances, the first one you should look at is our S600-34 spiral balance with a black tip. The second, however, would be our S600-37 with a black tip, but that color option is not available for that length Series 600. Therefore, that balance will have to be custom made.

With that said, I'll go ahead and email you a custom order link that you can use to place an order on our website. 

The diameter of the cam for the 15-048 is approximately 5/8", while the width of the slot is approximately 3/16".

You will want a red tip for both 34" and 37" balances. A red tip for these balances will carry a window sash weight range of 12 through, and including, 30 pounds.

Thanks for getting back to us, Kevin! I'm glad to hear that the balances worked.

A black tip should work for both of your balances. For the S600-34, a black tip will carry a sash weight range of 31 through, and including, 40 pounds. For the S600-37, the black tip will carry the same.
