Don’t let some jerk steal your bike (or skis, or whatever)! We've combined our Cable Anchor - Window with a sturdy cable lock. Since SeaSucker bike racks aren’t 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.
