Don’t let some jerk steal your bike! Since SeaSucker bike racks aren’t bolted on to rooftop bars, we came up with our Cable Anchors. A Cable Anchor is just what it sounds like – an anchor point to securely connect a cable loop to your car. The Cable Anchor – Trunk has a steel rod that closes inside a trunk or hatchback seam. The Cable Anchor – Window slides over the glass and rolls up into the window frame. Each is made of polished stainless steel and has a wide 1.375″ hole to thread a cable lock through. The Cable Anchor Trunk is plastic dipped to protect your car’s paint.
