This is a large mirror that is clamped to the mounting pole and secured by bolts. Easy to install by simply clamping the shaft with a 1.1 inch (28 mm) diameter. Even if the diameter of the pole is slightly thin, it can be installed using rubber plates, hoses, etc. 2 mirrors are stored in 1 frame, so you can expect a safe work of work, up and down, left and right. Also, buyers contact us if they can be used as a replacement for the German large tractor FENDT mirror. It also has other versatility, so it can be used with a variety of machines. Even fragile mirrors are similar to consumable parts. You dont need to have a quality but expensive genuine product, and it is good for aftermarket. Comes in a set of 2.
