A hose sleeve is designed to protect the work surface from scratches during the work process. As a number of our tools can be connected to a dust extractor by means of a hose, it is important to make sure you are not accidentally scratching the surface when dust is being removed. For this reason, we have introduced a special hose sleeve with a soft surface, so that the chance of scratches is reduced. The hose sleeve also works for routing the power tool cord at the same time.
