Never before have you experienced an easier system for controlling the dust from handheld power tools. This kit offers all the features of our well-loved FlexiPort system, plus the Click-Connect feature for fast, easy switching of a single hose between multiple tools! Leave the included rubber Click-Connect FlexiPorts on your tools and switch the hose from port to port with a secure ''click.'' The kit includes four FlexiPorts of varying diameters, plus the Click-Connect Hose Adapter, which threads into the included Expandable Hose (now in blue). The blue hose is lighter in weight than the older black hose, for less tendency to pull on your tools. Three of the four FlexiPorts have a clasp that you can ratchet down for a secure connection to the tool. Finally, a vent collar lets you adjust the suction level—perfect for reducing swirl marks when orbital sanding.
