Not bulky or heavy. Comes with lock and two keys, handy carry bag. Determine your coupler size, add or remove outer shells of the ball to achieve your ball size. Insert into the coupler and close the tongue latch. Insert the pin lock through the latch and slide lock over pin until tight - this helps prevent compromise from bolt cutters or pry bar.
