The small locking device on the left is suitable for use on the JR, JRH, JRPH/L (1/4″) and JB models. The larger device on the right is to be used on the JRPH/JRPL (1/2″-1″), JRHF and JBDL.
The base of the two piece design remains in place once applied and will not interfere with normal operation. The device is compact, highly visible, easy to use and made of durable polypropylene.
A method of preventing unwanted setpoint changes is to use a lockout device, and our new lockout device for J-Series regulators is a perfect solution. This lockout device will easily and effectively secure a manually actuated regulator.
