The bearings in the rollers on our Quonset doors have finally all fell apart and it is painful to open. I've contacted southwest steel in Moose Jaw and they were going to come out and replace them... 4 weeks ago. I guess they don't need my business because they don't return/answer calls. Does anyone know where a guy could find 4 new rollers in Saskatchewan? Or anywhere else for that matter? The Co-op carries them but they are lightweight and wouldn't hold up.
