Condensation and the rust it brings on are all too often the results of ordinary machine covers. This HTC cover is of a strong, durable cotton sheeting that is skip-coated with a special plastisol. The resulting cover is water resistant, but breathes so condensation doesnt collect. The covers have the hems rolled around the entire perimeter, with a rubberized magnet sewn into each corner. These durable silver-colored protectors are useful around the garage, shop and house, but are sized for woodworking machinery.
