Side window panels for Bobcat "M" Series. Please inquire about your specific make and model. These window panels are custom made for each Bobcat M-Series machine. They are made out of Lexan (a poly-carbonate material) and they are a little more than 1/16`` thick. They come with a foam weatherstrip around the whole window to make a seal on your machine.These side windows are also stationary and they do not slide and come pre-drilled in cost cases. These windows can only be mounted to the outside of the cab.
