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. Choose standard (6' cable, suitable for most applications), or XL (10' cable, especially for our Classic Ski Rack).
