Armaclad pivot and balancer

Hello there. I believe this might be a 15-140 Balance Shoe, which works with Series 150 Coil Balances. You will need to remove your old system and compare to these parts to confirm it matches what you have. The video below shows how to remove and replace a similar setup. Let me know if you have any questions.

Hello again. While this coil balance system is modular, meaning you only need to replace the parts that are broken, we find that for the springs themselves its usually best to replace all of them for one go. The reason for this is when you mix new coil springs with old ones, the new ones tend to wear out faster. It's sort of like mixing old and new AA batteries. At any rate, for the Series 150 springs you need to select spring weights for each individual coil you replace. The spring weight designates the weight each individual spring can support. Stamps on the springs, usually near the tongue, indicate this--but if there are no stamps, or you are uncertain, give us the exact weight of the window sash this system supports. I can work out the spring weights you need from there.
