Hi, I'm going to need several of the same part to replace the balance on my double hung vinyl windows. The number 7 is marked on the coils. Some the coil is broken and some just the coil housing is broken. I would like to get part numbers for each scenario.
Thanks

Hey there,
We do not have an exact replacement for this assembly but the 15-140 Coil Balance Shoe and Series 150 Coil Balance should work for the repair. To confirm that the shoe will be a fit, carefully look over the specifications below.
Since your coils are marked with a 7, you'll need the S150-7 to replace them. The supports for this coil are made using the 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and 15-145 Coil Support Barrel.
