Hey Nancy. This appears to be our 15-102 Double Side Load Carrier. This carrier contains our Series 145 Coil Balances. The springs are the actual components that regulate the window movement. If any are missing or torn you will need to replace them. To replace specific coil springs, look for a stamp on the spring tape that indicates their 'spring weight' or the weight that they are designed to support. If there are none or you are unsure, give us the exact weight of the window sash that these assemblies support, and we can work out what you need. |

We don't have a video tutorial for these, unfortunately, but I will try to summarize the installation process as clearly as I can. These coil springs install differently than other assemblies in that the coil attaches directly to the jamb itself. This presents a unique type of installation.
Hopefully this information helps you. Please feel free to reach out if you had any other questions. |
