The 99713 is designed to provide superior airflow in a lightweight design to address the two features most desired in a central vacuum on/off control hose. The 360 degree swivel handle is designed to reduce kinking, stress on the hose, and stress on you as the user by relaxing any tension in the hose as you move through the room. The 35 foot length provides extra reach and insure there is sufficient length to prevent tugging and pulling to reach to the corner of the room. The installed hose sock is designed to reduce the possibility of marking walls, floor, or furnishings while also avoiding wear to doorframes and chair legs. The hose is compatible with industry standard central vacuum inlets including Nutone branded valves equipped with low voltage contacts in the opening of the inlet valve. You can confirm suitability by putting your finger into the hose opening and confirming there are two low voltage contacts on the upper surface of the opening. No need for concern as these contacts are low volt and will not harm you in any fashion. The 99713 is compatible with all major brands of central vacuum including Eureka, Beam, Electrolux, Vacumaid, Canavac, Hoover, Cyclovac, Husky, Vacuflo inlets with pin jack inlets, M S, MD, Imperium, and most regional brands.
