Capitol Window coil balance and support

It appears your inquiry was cut off from the beginning, but we believe we know what you are looking to replace. Take a look at the following parts that should be able to be used as substitutes for what you have right now: our 15-180 coil balance shoe, 15-181 double support detent clip, and 15-182 balance bushing. Take a look at each part to see if you agree with our suggestions. These parts go with our Series 190 coil spring. You will need the stamped on your spring when ordering your coil. We placed some media guides on this page to offer some extra help if you wish to look them over.

The stamp should be near the end of the "tongue." If you don't see any, please weigh the sash and tell me how heavy it is. For coil springs, we would divide that among how many springs are on your window (in this case, 4) and choose the stamp appropriately.

Great, thanks for the info. Based on your 13 pound sash, I would use one S190-740 on each side. That should be sufficient. I'm not sure why you originally had two springs on each side for a sash that's only 13 pounds, seems like overkill.

As for the pivot bar, please compare yours to our 26-226.
