A manual operator for a coiling door has a reel mounted for free rotation on a shaft supporting drums to which the coiling door is secured. An endless flexible non-extensible element is mounted on the reel with a sufficient number of turns thereon for complete opening or closing of the door and the reel is secured to the adjacent one of the door supporting drums. The resilient non-extensible element is manually drawn to open or close the door and may be provided with hand holds to facilitate grasping thereof. A guide for the flexible non-extensible element may be secured adjacent the reel to guide the flexible non-extensible element onto and off of the reel.
