Review on CURT 45901: Adjustable Trailer Hitch Ball Mount - 2-Inch Receiver, 6-3/4-Inch Drop - 1-Inch Hole - 6,000 lbs Capacity by Leo Fairchild

This suits my needs very well as I lug a few things at different heights. It would be 5 if the locking screw could be used in the lowest position with the block upside down. Good product, durable, easy to use and set up, well made. Update December 2017: I am changing my review and rating: When trying to pull my pontoon trailer out of the lake it got stuck on the ramp. When we tried to lift it with some extra pressure on the car accelerator, the pin holding the top of the ball joint ripped completely out of the metal, meaning the metal ripped completely through the top right hole. The metal that the ball joint studs are attached to is not very strong. I do not recommend anyone to buy this device.
