I couldn't find any names, numbers or other window ID. Double hung window. The plastic cover for the coil is broken and is preventing full bottom half of window opening. I need a new plastic part

Hello there! Thanks for reaching out to us. We don't sell this exact coil cover but we may still be able to help. Can you show us a photo of the pivot shoe, preferably removed from the window? If we can ID the pivot shoe, we can determine the compatible springs.

This will do! This pivot shoe isn't something we sell but the 15-177 is very similar. The Series 152 are the compatible springs. If your old spring band is 1/2" wide, you may be able to use the 15-143 bushing, 15-144 cap, and 15-145 barrel which "sandwich" around the spring.
