B. The Outer Ladder Locks - Located at the tops of the outer ladder assemblies. There are
four of these on each ladder. They permit you change the height of the ladder (Fig. 16-17).

Since the outer ladder assemblies can be adjusted independently, setting them at different
lengths is how you achieve the 90-degree and staircase modes. You can also completely remove
the outer assemblies from the inner and link them together to create a scaffolding trestle.
WARNING:
WITHOUT AT LEAST ONE FLARED OUTER BASE ATTACHED. NEVER USE INNER OR
OUTER SECTIONS AS A SEPARATE STEPLADDER.

one of the following outer ladder lock styles:
a) ROCK LOCK
