Hello!
We need to buy springs for our windows. The photos are of one that fell out of one of our windows.
The exact measurement is 26 3/4 inches from plastic end to plastic end.
Thank you!

Thanks for posting. Can you confirm that the metal channel, not including the nylon fittings, is 26" long? Can you show me a clearer, closer picture of the bottom nylon shoe? From there I'll do my best to narrow this down for you. Thanks.

Thank you so much for your response!
Yes, the metal channel is 26" long.
I attached better photos of both ends (back and front).

Thanks for your new photos. Based on what I see here, you have either our S380-26 or S385-26, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
You will also need to weigh your sash to confirm the best stamp option, since your old stamp is a little outdated.
