You are buying a new pair of left and right side magnetic adjustable mirrors. This item will attach to anything you want to put them on that magnets will stick to that is metal,for example a skid steer, farm tractor, sub compact tractor,jeep,back hoe, bulldozer, track loader etc. I use these mirrors on my own equipment and they make backing up or seeing whats behind you a breeze.This makes the person operating the machine much more aware of his or her surroundings making a much more safe equipment operater. These mirrors have 2 neodymium magnets each with rubber covers to prevent scratching the surface you put them on. Each magnet has 24 pounds of force(48 pounds of force combined) for a very strong hold yet not to strong to where they will stay on and break. If you hit something these mirrors will fold and break off and they won't get broken. a piece of safety wire is recommended so you don't run them over in the event of them falling off of your machine. Your order will get shipped quickly and promptly after the order is placed. If you have any questions feel free to message me for any questions thank you!
