Can fixed breaker lock S29371 be used on a 2-pole HD or HG breaker?

Need breaker lock-off for a 2-pole HD or HG frame breaker.

Product Line:
Powerpact H-frame

Powerpact HD and HG 2-pole breakers use a smaller frame than 3-pole HD and HG breakers and 2 and 3-pole HJ, HL, and HR breakers. Need a breaker lock-off that will work with this smaller frame.
S29371 can be used to lock 2-pole HD and HG breakers OFF or ON. For a fixed lock OFF only, use part number H2PHLA. For removable lock OFF only, use S29370.
