Reviews Description: Is your garage filled with so much stuff there's no room for the car? Here's a practical solution. Go vertical! The Harken Hoister allows you to store car top recreational equipment such as kayaks, dinghies, and tenders up and out of the way. A self-locking, ball bearing block system prevents accidental release even if you drop the line, and allows you to hoist and lower large items onto your car by yourself. System comes with every thing you need for fast installation.
