Searching for Chanel balance 2240

Hello and thank you for writing in. Based on the photos of the nylon fittings on both ends of your balance, leads me to recommend our Series 390 channel balance. This comes assembled with a 19-002 balance top and 15-001 bottom balance shoe. Carefully compare your nylon fittings with ours. The nylon fittings are crucial when locating a replacement balance. We can't emphasize enough the importance of going over our measurements to make sure they match up with yours. If everything looks correct, then you can go with the S390-23 with a 2240 option for the 23" balance and S390-29 with a 2830 option for the 29" balance. Review this over and let us know if any other questions come up.
