Carriage Assemblies are essential garage door hardware for overhead style garage doors. Trolley Carriages attach to the garage door rail across the ceiling and attaches to a chain, cable, or belt to lower the door closed or push it open when the opener is activated. Screw drive operators, chain drive operators, and belt drive garage door openers all require carriage assemblies to open and close doors.
Our collection of genuine LiftMaster operator carriage assemblies include options for a number of different operator types by LiftMaster Chamberlain. If a door is having trouble opening and closing via mechanical issues, a carriage assembly may need to be replaced.
