Abstract: A dispenser for dispensing flexible sheet material from jumbo-sized rolls. The dispenser includes a housing containing a roll to be dispensed, and protecting the roll from the environment and from vandalism. The housing includes an opening at the bottom thereof to permit a user to withdraw the flexible sheet material. The dispenser includes at least one support roller adjacent the opening. Each support roller supports the roll by its lower periphery, facilitates the rotation of the roll, and maintains a portion of the periphery of the roll adjacent the opening. The housing further includes a wall, with a guide track, which is mounted to a restroom stall wall or another supporting surface. The dispenser also includes a guide mandrel which is slidably retained within the guide track, and is located inside the hollow core of the roll of flexible sheet material.
