This lockout device jams the valve lever release trigger. (Place UBFVL between the valve lever and release trigger & hinge open until the two parts jack the valve lever and release trigger to a frizzed position).
Use a ES - GTML + 2C cable lockout (Order Separately) to secure the device in place by passing the cable around the valve body and through the matching hole of UBFVL.
Place the padlocks on GTML and secure the device.
This product is also known as butterfly valve handle jammer.
