A trolley for use with a folding door to suspend the door from an overhead track. The trolley has a mounting post for use in connecting the trolley to a folding door with a cylindrical mounting axle extending from the post. The trolley has a wheel unit comprising a short wheel axle with a wheel rotatably mounted at each end. The wheel unit is mounted on the post with the mounting axle on the post extending through the wheel axle between the wheels. The post is rotatable relative to the wheel unit.
A drum for a roll-up closure, the closure having a door of hinged together slats, one end of the door adapted to be mounted on the drum, the door adapted to be wound on the drum as the drum is rotated. The drum has a wall defining its shape with a depression in the wall extending both inwardly and across the width of the drum. The cross-section of the wall defines an increasing spiral from one side of the depression to the other side of the depression.
