Replacement bathroom coil balances

I'm afraid those numbers don't tell me much about the support itself, or even the balance assembly. In order to make a recommendation for you, I will need two pieces of information:

• A photo of the pivot shoe
• The width of the coil spring band

Once I know that, I can tell you what plastic cover would be best for this project.

Thanks! This pivot shoe appears to be a match for our 15-199. Since your spring is also 1/2", I recommend the Series 160 to replace it, along with the 15-150S single spring retainer.

Please let me know if you need anything else!

That would be the 15-150S single spring retainer that I mentioned. This is designed to work with the Series 160 coil spring, so as long as that matches then the 15-150S will work perfectly well for your application.
