GETTING TO KNOW YOUR LADDER
The Alta-One is made up of three major components: one inner ladder assembly and
two outer ladder assemblies that telescope over the inner. The inner and outer
assemblies work together with the Triple-Locking hinge and the lock tabs to adjust
the ladder into different lengths and positions, including an A-frame or stepladder, an
extension ladder, a staircase ladder, a 90-degree ladder and trestles for scaffolding.
Each rung has slip-resistant treads, and each leg is equipped with rubber feet for
improved traction.
Inner and Outer Assemblies. When the ladder is in its storage position, the inner
assembly remains inside the outer assembly. To raise the ladder’s height, simply
release the lock tabs and telescope the inner assembly upward and then
lock it in place at the desired height using the lock tabs on each side of
the ladder. To lower the height again, telescope the inner assembly
back into the outer.
Triple-Locking Hinge. The hinges are located at the
top of the ladder on each side when in the storage
position. The hinges unlock so you can adjust
the ladder into different working positions. To
Understand how the hinges work, follow the
instructions on back to adjust the ladder from
its storage position and into a working
position.
Work Platform (optional). The versatile
Work Platform fits on the rungs of any
Little Giant multi-use ladder and is rated
to hold up to 250 lbs. Use it as a tray for
a paint bucket or tools, or use it as a
sturdy, comfortable standing platform.
Now you can stand on your ladder for
extended periods without sore feet and
bruised shins, and you can work with
both hands in any direction. The Work
Platform also serves as a stabilizing
spreader bracket for your Little Giant
Alta-One’s trestle-and-plank scaffold-
ing system.
