Mine is set up that same way on right handrail. The thin piece of sheet metal fits snug into the plastic bracket on back on the monitor and doesn't shake around.You may wont to cut a small strip of some kinda rubber to put under the U-Bolts so doesn't scratch your handrail if that kinda thing bothers you.They also make a suction cup backet can put on the window but I have heard they come un-stuck when bouncing around a lot but that's just what have heard,so never have used mine that come with baler...
