[align:left][/align] Has anyone else encountered an issue with GAL door tracks and hangar rollers? On the past few mods that we have completed, the rollers sound really rough on the track, and after about a week of use there is a black coating on the rollers that seems to have flaked off of the door track itself. The coating is causing flat spots on the rollers which keeps the hoistway doors from closing completely and faulting out the controller. On mods where we have reused the original track, the doors work smooth as silk. Contacted GAL and have been told that they have not had anyone reporting similar issues.
