The Master Lock® device is used to surround the valve operating handle (T-bar) of the SDBB in order to protect against accidental valve opening. The unique rotating design allows for easier installation in confined space applications.
The tough dielectric Zenez™ Thermoplastic body withstands chemicals and performs effectively in extreme conditions.

All our SDBB valves can be ordered including the Master Lock® device.
