Review on 🔧 Prime-Line Products B 610 Spring Tension Roller Assembly: 1" OD, Concave Edge, Steel Ball Bearing – Convenient & Durable Option by Todd Mohr

If you have such a wheel in your sliding door, I wish you luck in getting out the old broken plastic wheels. I was about to grab a sledgehammer when I remembered YouTube existed. I'll spare you the search. https://www.youtube.com/watch?v=DOcRAbkcAe8 Rollers are infinitely better than the old plastic rollers. The door now actually slides instead of sliding down the path like a pinto ford over cobblestone steps. Even if your plastic casters haven't broke yet, I would recommend making the switch. The door has never rolled so well, not even a new one.
