Pella retractable sliding screen




Thanks for reaching out to us! It sounds like you may need to replace either the Pella Trolley or the return spring. I'm sorry to say we would not be able to supply you with replacements for these parts as they've been discontinued from our inventory.
You may have some luck contacting Pella directly or a local Pella dealer but I cannot make any guarantees. At the very least, they may be able to provide you with the schematics of the door; unfortunately, that is not something we have either.
Our sincerest apologies that we could not be of more help with this repair but please don't hesitate to reach out with any other questions.
