ACCESSORIES
BANDS
The H-3439 and H-3440 Circuit Breaker Lockouts work with the majority of
breakers found in industrial facilities. However, in the instance of a breaker
with an odd-shaped toggle, it is recommended to use one of the enclosed bands.
Place one or more bands over the breaker toggle, then apply the Circuit
Breaker Lockout. (See Figure 5)
METAL CLIPS
For double or triple breakers with a metal tie bar, it is recommended to use
the metal clip included with the H-3440 Circuit Breaker Lockout. Slide it over
the adjustable jaw of the H-3440, then apply the device to the breaker. (See
Figure 6)
