Hi I need these 2 balancer the L9 and R13 used in the same window.
I have 2 more exact same windows that need replacement but haven't taken them apart. Is it reasonable to assume that the balancers are the same ?
I would need a total of three sets.
Thanks
Ed

The L9 balance is 24-L9-1327 and the R13 balance is 24-R13-927. As long as the other windows are the same size, and the sashes match, then the balances would be the same.
