Replacement screen door wheels rollers

Wheel1

Question:

The screens and frame are fine. The wheels are rusted. Where can I get replacements and are they hard to install?

The only hard part is getting them free from the rust. Spray the roller with penetrating oil and let it sit for 15 minutes. Repeat the application until you can unscrew the bolt that holds the roller in.

That roller looks like a 1-3/4" diameter bearing, if you cant find one at your local glass shop, contact me and I will supply it for you.
