Review on Trimax TAR300 Anti Rattle Receiver Locking by James Arellano

Rattle-resistant locking pin that looks good from both the top and bottom, and this pin fits perfectly. The locking mechanism is smooth and durable. I leave the rack on in the elements for a few days and it doesn't stick or act weird. The included wrench leaves a bit to be desired, but you don't have to over-tighten the pin to round the end. To make it work with my Allen bike rack (4 bikes with 2" hitch) I had to drill one side of the pin holes to allow the large threaded portion of the pin to reach the lock nut on the inner panel. This works great and provides consistent rack stability and is more secure than using the included hex screw while also being easier to install.
