Developed in England as the ultimate high-tech door breaching device, the 'SAS Tool' is an electric/hydraulic jamb spreader and door opener. It exerts almost 7 tons of force automatically switching between spreading and breaking. Can be used on either lock side or hinge side, operating silently until lock breaks. The BrocoA(R) SAS Door Breacher exerts hydraulic pressure through the frame cylinder between opposing faces of a door jamb in order to provide necessary support and resistance for pressure applied through the door piston to force the door open. A hydraulic diverter valve within the tool automatically ensures the unit reaches correct pressure to hold it firmly before the door cylinder begins to pressurize. The SAS Breacher consists of a rechargeable 24v hydraulic power pack, ten foot hydraulic lines with no-spill quick connects and dual piston door opener. The SAS Breacher is for inward opening doors only.
