Cable Anchor Window/Lock ComboDont let some jerk steal your bike! We've combined our Cable Anchor Window with a sturdy cable lock. Since SeaSucker bike racks arent bolted on to rooftop bars, we came up with a way to keep your bike safe. A Cable Anchor is just what it sounds like an anchor point to securely connect a cable loop to your car. The Cable Anchor Window, slides over your window glass and rolls up into the window frame. Not recommended for tinted windows.
