Hello, Thanks for posting! The loud bang you heard was likely the coil balance breaking in the window channel. So, you'll probably need to replace the entire assembly. The balance coil and the compatible plastic pivot housing work, in tandem, to support the weight of the sash and help the window to open and close. We do not carry an exact replacement match for your existing support but our 15-251 Inverted Universal Single Support should work well as a suitable replacement. This support is compatible with the Series 160 Coil Balance. Since, your support is stamped with a 9, you'll need the S160-9. I am not certain if your metal bracket will be compatible with the inverted universal support, so you may need to consider purchasing the 16-032 Mounting Clip to complete your installation. 
Measurements of 15-251
In regard to the method you use to remove the assembly, you will need to use your discernment to determine which is the best for completing your repairs. Be sure to review the videos again for reference. |

My pleasure to assist! When assembling the inverted universal support, the coil rests in the support (in your case the 15-251). Then the coil would extend to the top of the jamb to hook onto the 16-032 Mounting Clip, which is designed to take the "T" shaped tab on the Series 160 Coil balance. You will need to replace both of the assemblies in the window to ensure the window continues to functions properly. I hope this helps! |
