Pella screen door hanger
Hello! This part looks very similar to our 84-105 Pella sliding screen door roller. Please review our photos and information for this product and let me know if you agree.
You're welcome! Please let us know how it works out.
To remove the 84-150 roller, you have to first partially remove the door by lifting it up and sliding out the bottom. Then, locate the adjustment screws on each side at the top of the frame. Turn them clockwise until you can remove the broken part.
To install the new roller, simply reverse this process.
We think we are missing the adapters use to connect to the spring. I am attaching photos. We have looked at videos but don't seem to have the parts
I'm sorry to say that much of the hardware used on this door is no longer available to us, especially that spring trolley you show in your second photo. My recommendation is to contact a local store that deals in Pella parts. They may have older hardware still in stock that you can use to repair your door.
