The Thermal Dynamics Nylon Cover for Cutmaster 38 & 39 (9-7070) is a mildew-resistant, odor-free, water-resistant forcefield that keeps your Cutmaster out of the elements.

That might be overstating it just a bit. It's a nylon cover that keeps your Cutmaster from getting dirty. Will it protect it from a meteor? Nope. Will it keep the dust off? You bet.
