Many home owners have had their home roughed in for a central vacuum but after they move in they discover that the builder didn't consider furniture placement while planning the location of the inlets. Now they have a corner of the bedroom or ensuite where the 30' standard hose won't quite reach. This product will now allow you to use your standard length hose and when you need that extra reach you can connect this hose instead of having to re-locate or add another inlet. This extension hose works with all central vacuum hose types including those with on/off capabilities. If you use an electric power head you will need an electrical extension cord so the power cord extends alongside the hose.
