Shutters for sliding glass doors can be conveniently mounted using a bi-pass track system. A traditional shutter is hinged and folds into a room, often creating space considerations. A bi-pass shutter has heavy duty rollers attached to the top of the panels which, in turn, glide smoothly back and forth on tracks mounted at the top of the slider. The bi-pass shutter is finished with decorative fascia on both the sides and top of the frame which both conceals the system's hardware, and also provides the classic shutter look in a sturdy, elegant, and practical fashion.
