Hi,
My ACME rollers periodically bend out and spread open enabling the wheels to jump the track, which requires significant effort to remove, bend them back into shape/position, and then reinstall them. They are easily bent indicating an aluminum or alloy pot-metal fabrication. Is there a heavier duty roller assembly to replace them with that would use the existing track? Tearing open the wall to replace the track is not a desired option. Thank you.
