Sliding Doors are always subject to high winds. Over time, these wind pressures can weaken the horizontal framing members (called “girts”) on the doors. In extreme cases, these girts can become permanently bowed. When the girts become permanently bowed, the door will rub on the jamb during the open and close cycle and the door will be difficult to operate. If the girts are weakened, the doors will typically only be hard to operate during windy conditions.
At Power Track, we have developed a product to eliminate this problem. Our unique and exclusive Roller-Guide System creates a barrier between the door jamb and the door girts that is buffered by a high strength roller bearing. This allows the door to move smoothly during conditions that would typically be difficult to operate.
In the video, notice the marks on the door girts where the wind has pushed the door into the jamb causing it to open with extreme difficulty. With the Roller-Guide installed, this is no longer a problem area for this customer’s door.
