A keyed door provides access to the stock Harley-Davidson Dzus fasteners. Once the door is closed and locked, you must have a key to access removal of the bags. When the access door is closed, pressure is applied to the head of the Dzus fastener, the main housing incorporates an anti-rotation system that is designed to apply pressure to the bail portion of the fastener. This prevents rotation. By applying pressure to the head and preventing rotation with the bail, this system virtually eliminates the possibility of your bags falling off. Another asset to this system is, by using a keyed lock, when the door is in the closed position no one without your key, can access the removal of the bags, making it the only theft prevention system available.
