The Libervit HR7 is a hydraulic jack designed to open PVC, wooden or metal doors, single or multi-locks opening inward, when 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 jack requires either one of the Libervit hydraulic power units or a LIBERVIT hand pump. Two control switches on the tool activate the HR7 jacks.
