Hooks are designed with a rubber coating to protect from scratches | Easy to install and easy to use | ROBUST ENGINEERING - New improved STRAPS eliminate the fragile hooks that plague cheaper hoists, and allow you to lift heavy products, up to 125lb. Capacity. This is the kayak hoist that all the other are trying to copy. | For Ceilings up to 12ft, you can mount this item as pictured on a 2 X 4 and screw the 2 X 4 to the joist or mount it right to the joist itself | Safe locking mechanism prevents accidental release
