A simple mounting bracket design uses your hitch ball as its mounting bolt with a custom designed washer that prevents movement once securely tightened. Works with most receivers up to 3" wide and fits balls with up to a 3/4" shank. As it mounts to the receiver ball mount, it fits with both horizontal and vertical receiver hitch assemblies. A quick release design allows quick removal by simply removing the 2 locking pins and sliding the rack free of the mount to accept your trailer. Made from durable powder coated steel, this rack will give years of service and hold up to harsh road grime. Its open tubular design brings this durable rack in at barely over 6 lbs. Universal fit.
