Balance parts for Lax windows

Hey there,

Thanks for posting! Your balance assembly appears to be an inverted coil balance assembly of some sort. I believe you can use our 15-251 Inverted Universal Single Support, however you'll need to carefully review the hardware to confirm this will work as a replacement. Please let me know if your assembly uses more than one coil balance spring.

The coil spring compatible with this support is the Series 160 Coil Balance. To confirm the exact coil needed, you'll need to check for any stamps/markings that will indicated the spring strength needed. For example, if your coils are stamped with a 9, you'll need the S160-9. 

If there are no stamp/markings or they are hard to read, you'll need to obtain the exact weight of the sash and divide it by the total number of coils in the window.
