We have been working with a local facility to develop a new Shower Safety Knob designed to discourage attempts at self-harm. Currently it fits directly onto Powers(c) brand (Hydroguard Series 410) valves that were used at many NY facilities like Prisons and Psychiatric units. We were brought in on this because the current solutions were just not practical with soapy hands. Our design solved the slippery issues and even looked better. We are in the process now of fitting the design to other Valve brands and Styles.
