Replacement parts

A home owner from USA says:
I wanted to know if these constant balances can be replaced with the 140 singles? I replaced these less than 8 months ago and they broke again. This type of shoe makes the window very hard to remove and install. These old balances are very poorly designed.

I cant seem to get your upload link to work. As stated in my previous email, I would like to know if I can replace the existing springs and shoe with the 140 singles. I understand that I may need to replace the tilt bar also. The reason for my request is the existing system is poorly designed and has broken twice now. The window is extremely difficult to remove and reinstall due to the way that this shoe is designed. I have attached photos of the tilt bar, broken spring, and window channel. Thank you for any assistance you can provide.

Thank you for submitting your inquiry to our discussion board.

For a 15.5 pound sash, you can use our S140-8 Quick-Tilt coil balance system with our 26-398 pivot bar.

Also, take a look at our 26-408 tilt latch pair.

Compare the dimensions of our parts with what you currently have and see if these recommendations will work for you.
