NFRC replacement part

Hello there!

The part shown here is called a coil spring support. We may be able to help with this but we'll need more information. Can you show us a photo of the pivot shoe, preferably removed from the window track? Identifying the pivot shoe will allow us to determine the compatible spring and coil supports. 

Thank you for the additional photos! The pivot shoe shown here is the 15-177 which uses the S152 coil springs. For new spring supports, see the 15-143, 15-144, and 15-145. These parts "sandwich" over the spring. 

As for the vent latches, see if the specifications of the 26-122 match what you need. 

Let us know if you have any questions!
