Designed to open wooden, metal or PVC doors, single or multi-lock inward opening doors, the HR7 is placed horizontally between the door’s vertical frames. A handle on the jack gives a better grip. It has an exclusive telescopic rod system with a “Extend” quick-lock and it can be adjusted in length to reduce installation time in front of the door. For power supply, the HR7 requires either one of the LIBERVIT hydroelectric power units or a LIBERVIT hand pump. Two control switches on the tool activate the HR7. An adapted hydraulic hose is needed to connect the tool to the hydraulic power unit or hand pump.
