For heavy-duty jobs, nothing beats the Super Duty
Type 1AA Little Giant Ladde

When you need industrial-strength, only one ladder will
do—the Little Giant Type 1AA. It’s government rated
to a whopping 375 pounds, so you know it can stand up
to even the most demanding applications.

And because it’s a Little Giant, the Type 1AA gives you
the advantages of traditional A-frame ladders, extension
ladders, stepladders and even scaffolding—all in one
convenient package.

The Little Giant is designed to be the safest ladder on
the planet. Since it’s adjustable, the Little Giant can
be used safely on stairs, ramps, curbs, docks or other
uneven surfaces.

The Little Giant is made of heavy-wall, 6005-T5
aluminum—the very same material used in aerospace
construction. So it’s ultra-strong while remaining light
and portable.
In fact, The Little Giant Type 1AA is government-rated
to hold up to 375 pounds, but has survived brutal stress
testing of up to 1200 pounds with absolutely no
structural failure.

Little Giant Type 1AA Features:

* Heavy-wall aircraft-grade aluminum construction
* Rated to hold up to 375 lbs.
* Combines 24 different ladders into on convenient system
* Lightweight and portable
* Complies with all applicable OSHA ANSI A14.2
* Includes a full Lifetime Warranty

No other ladder gives you the versatility of a Little
Giant. Independent tests prove the Little Giant will
replace 60-70% of all portable ladders currently being
When you buy a Little Giant, you’re not just getting one
ladder. You’re getting 24 different ladders combined to
make the world’s most versatile ladder system.

Little Giant Ladder Configurations:

A-Frame Ladder
With a simple click of the patented hinge, the Little Giant can be used as a
traditional A-Frame ladder.
A-Frame Ladder
Staircase Ladder
Because it's adjustable in one-foot increments, the Little Giant allows one side
of the ladder to be extended allowing safe use on uneven surfaces like staircases,
curbs or docks.
Staircase Ladder
90° Ladder
Traditional ladders make working close to walls nearly impossible. With the Little
Giant, one adjustment allows you to safely work against any vertical surface.
90° Ladder
Extension Ladder
For large projects the Little Giant easily converts to a stable extension ladder allowing you to reach rooftops, tree limbs and more with ease.
Since the Little Giant pulls apart to form two scaffold trestles, you just add the Little Giant work plank (sold separately) to form a convenient scaffolding system.

Operating Instructions for Little Giant Ladder System®

A. The Hinge - located at the top of the ladder when it is in storage position, permits you to alter the shape of the ladder.
The hinge locks in the following positions (See Figures A-1, A-2, and A-3).

Figure A-1
Figure A-2
Figure A-3

1. Unlock the hinge by pushing straight in on the Palm Button until it stays in the open (unlocked) position on both
hinges (See Figures A-4 and A-5).

Figure A-4
Figure A-5
a. NOTE - If there is pressure on hinge lock pins it will be difficult to unlock the hinge. To relieve pressure,
simply adjust one half of the ladder back and forth until hinge lock pins move without force.
b. NOTE - DO NOT FORCE HINGE LOCK in or out with any tools as it will cause permanent damage to
the hinge mechanism. It should never require more than light pressure to unlock the hinge if the holes are
properly aligned.
2. You may now open the ladder to the A-frame position by pulling the two ladder halves apart until both hinge lock
pins snap into the A-frame locked position.
3. Now place the ladder into the extension position by again pushing straight in on the palm buttons of both hinges
(See Figures A-4 and A-5).
Rotate either side of the ladder until the hinge locks snap into their locked position.
To restore the ladder to the storage position, reverse the above procedure. The hinge lock will lock automatically at
the A-frame configuration to prevent damage to the ladder or injury to the user.
Use caution and do not let the full weight of the ladder fall on the hinge lock as the ladder folds from extension to
A-frame configuration. Disengage the hinge locks in the A-frame position and return the ladder to its storage position.
B. The Lock Tab Assemblies- The second mechanical component of the ladder system is the LOCK TAB
ASSEMBLY. There are four of these on each ladder. These permit you to change the height of the ladder (See
figure B-1 and C-1).
Figure B-1
Figure C-1
Figure C-2
C. Adjusting the height of the ladder for use in the A-frame position.
1. Unlock both hinge locks (See figures A-4 & A-5).
2. With the ladder in the storage position and while holding the inner ladder assembly firmly in place, pull the four
Lock Tab Assemblies out of the rung holes of the inner ladder and rest them on the side of the outer ladder rail
(See figures C-1).
3. Raise the inner ladder up to the desired height.
4. At the desired height align the outer holes with the nearest rung hole of the inner ladder assembly.
5. Holding the inner and outer ladder at the aligned height with one hand, reinsert the opposite Lock Tab Assemblies
into the rung holes with the other hand.
6. Alternate hands and perform the same operation with the other Lock Tab Assemblies (See figure C-2).
7. Open the ladder to the A-frame configuration by pulling the ladder halves apart until the hinges lock into place
(See figure A-2 and A-4).
8. To return the ladder to the storage position, reverse the procedures and position as seen in Figure A-1.
D. Adjusting the height of the ladder in its extension ladder position.

1. From its stored position, unlock hinge (as indicated in figures A-4 & A-5)
and rotate to extension position until both hinges lock into place.

NOTE: Hinge will first lock in A-frame position, repeat unlocking hinge to
rotate its extension position.

Figure D-1
2. If equipped with wheels, wheels must be at the top of the ladder while
in the extension position. Unlock Lock Tab Assemblies on upper half of
the ladder. Grasp the outer ladder, walk backward, allowing the ladder
to telescope to the desired height. If more height is desired, extend the
lower half of the ladder (see figure D-1).
Figure D-1A
3. To store the ladder from its extension position, reverse
the above sequence starting with the lower half of the
E. Staircase Position.
1. Adjust ladder to desired height (review section
concerning adjusting the height of the ladder for use in the
A-frame position.) If equipped with wheels, the wheels
should be placed on the bottom of the long side, not against
the stairs.
Figure E-1
2. Then adjust the side desired for proper alignment to fit the
staircase (see figure E-1).
F. Scaffolding Trestle Operating Instructions
1. Pull the inner ladder assembly completely out of the outer
ladder bases (see figure F-1).
2. Open the inner ladder assembly to the A-frame position until
both hinges lock (See figures A-4 and A-5). This is the first of
two trestles needed for the scaffolding function (see figure F-2).
3. Grasp both outer ladder bases (see figure F-3).
4. If equipped with wheels, turn ladder without wheels 180º and
insert lock assemblies of that base into the adjacent holes of the
opposite outer base (see figure F-4). Wheels should be facing
out (see figure F-5).
Figure F-1
Figure F-2
5. Grasp the outer ladder base with the unused lock assemblies
and lower 1/2 inch, then spread the opposite outer ladder base
to form a second A-frame trestle (see figure F-5 and F-5
6. Rotate forked ears on work platform to position indicated
in figure F-6.
7. Insert work platform between outer ladder bases on the
third rung down of each base. The wire-formed end of the
work platform should surround the outer rung turned to the
inside of the outer ladder A-frame trestle (see figure F-7).

Doing this step
incorrectly may cause
damage to ladder.

Figure F-5
Figure F-8
Figure F-9
8. Press down on top of work platform until it locks in a horizontal position. Outer ladder A-frame trestle is now
ready for use as second trestle (see figure F-8).
9. Space the two trestles and place an appropriate scaffolding plank on the set of rungs at the desired working
height (see figure F-9).
G. Work Platform Operating Instructions
1. Tighten or loosen bolts until brackets move stiffly (see figure G-1).
2. Adjust to fit ladder rung (see figure G-2).
3. Place platform at desired height (see figure G-3).
4. Push platform forward and step up through the rung above platform (see figure G-4).
Figure G-1
Figure G-2
5. Push platform back with toe (see figure G-5) until the forward tip of the platform rests against the rung.
6. Check to ensure platform is securely in place before putting full weight on it (see figure G-6).
7. When through, step to rung above work platform and push work platform forward with toe. Step down
through work platform (see figure G-7).
8. The above instructions apply to the A-frame ladder also. The platform may also be used as a utility shelf
(see figure G-8).
