Siemens 2.3 Emergency Exit Device

This knob is designed to take off the Siemens emergency escape hatch door knobs in a HURRY. Made from Carbon Fiber reinforced Nylon, these are as durable as possible. The plastic knob will crack before this thing does. This cuts MINUTES off of any emergency escape or rescue using the escape hatch. Simply throw this tool on any 1/2" drive impact or drill and get to work
