Can the operating handle of a LA400AWK circuit breaker enclosure be padlocked in the ON position?

Need to lock the handle of the LA400AWK enclosure for LAL/LHL breaker ON. 

Product line:  
Circuit breaker enclosures

L-frame breaker NEMA 12/3R enclosure

The provisions to padlock the operating handle in the ON position is not a standard feature of the enclosure. A factory special modification can be ordered that will provide the padlock ON capabilities; add suffix SPLO to the standard catalog number. For field modification, a 3/8`` maximum hole can be drilled in the Lockoff Slider to allow the handle to be locked in the ON position. Check local code regulations for acceptability. Paint metal areas exposed by drilling with PK49SP touch up paint.
