The arrangement for dispensing a curtain using an extendable tube with mating rods and cartridges provides an expedient and convenient method for mounting, changing and removing curtains. It consists primarily of an extendable tube housing a cartridge for dispensing a curtain that is pre-assembled with attached circular balls and a guide piece. The cartridge is attached to mating rods that can be adjusted as needed to attach or remove additional cartridges. The user pulls the guide piece in a downward direction to release the curtain from the release chamber of the extendable tube. The circular balls spread along the sliding tracks of the extendable tube and the user can then spread the curtain as desired.
