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 between the following options: Standard 6' Key Cable Lock - 6' steel cable, suitable for most applications, includes five precision laser-cut keys. Standard 6' Combination Cable Lock - 6' steel cable with resettable 4-digit combination—no keys required. This combo gives your gear an added layer of security when you're parked and away from your vehicle. XL 10' Key Cable Lock - 10' steel cable, suitable for larger items and vehicles, includes five precision laser-cut keys.
