Spiral Balance Replacement

A quick learner from says:

Hello, I need to replace two spiral balances in my bedroom window. I have included a picture of a balance from another window. It has a yellow tip, I'm not sure what color I should replace it with. Also I will need the charging tool as well. Thank you so much for the help. Your website is wonderful!

Hi Jodi. Thanks for the kind words. Could you tell me the length of the outer tube, not including the colored tip? Also, I believe the diameter of the tube is 3/8", but can you try to confirm? I know it's hard with these older plastic tubes, since they're kind of flimsy. Just do the best you can. 

Finally, can we have a closer picture of the color tip? The balance from the other window has a tip that looks like it might be more off-white to me. White tip spiral balances are a bit tricky; in that case, it would honestly be best to place your window sash on a bathroom scale to give us the exact weight. We'll figure it out from there. Thanks.

Hello again. I've attached two pictures I hope it helps. Looks like the length is around 32 inches. But I'm thinking the width of the tube might be closer to a half inch. I hope that doesn't mean I can't find a replacement. I am a little nervous to take this balance off the window to weigh it as I don't have the tool yet to reinstall it. I hope this all makes sense. I can't thank you enough for all the help. I am very excited to possibly be able to get a replacement balance for my window. It is saving me from buying an entire new one?

Hi Jodi. It's pretty difficult to judge from this picture, but I'm almost certain the diameter has to be 3/8" or 5/8". The issue is that spiral balances with these older plastic tubes can be tricky to measure, since the outer tubes tend to get flimsy over time. Do your best to get an accurate reading; if you want, give me the diameter of the inner core, maybe just above the colored tip; we may be able to determine the correct diameter from that measurement too. 

Finally, I think this actually might be an off-white tip rather than yellow. White tipped spiral balances are a bit tricky, and to be honest it would be best to get the exact weight of your window sash. Simply lower the sash on a bathroom scale. If you're hesitant to remove the sash right now, you can try placing the scale on the sill and gently lowering the sash onto it. Let me know what you find.

Hi! Would you mind giving me a recommendation of which swivel to order with the knowledge we currently know on my window? I don't mind ordering a few different sets as they are inexpensive compared to installing an entire new window :)

Maybe a 32in - 3/8 diam - white spiral??

Fair enough! If the balances are indeed 32" long, you have two possibilities here: the S900-32 3/8" Spiral Balance and the S600-32 5/8" Spiral Balance. Neither have a white tip option, so I still suggest you still obtain the exact weight of the sash, and then match that exact weight with one of the weight ranges listed alongside each color tip option on the shop pages. Let me know if you have any other questions.
