The Quantum® from Little Giant® is made from lightweight aluminum and is easy to use, so you can focus on getting stuff done.
This ladder is a multi-position ladder, meaning, you can set it up in different configurations that suit the project at hand. Use the Quantum as a stepladder or extension. Set it up on staircases or in 90-degree or trestle-and plank* scaffolding configurations. With the sleek metal palm buttons, you will be able to effortlessly adjust your ladder.
Adjustable Ratchet™ Leg Levelers
With the optional attached Ratchet™ levelers, you can adjust the ladder’s legs in a hands-free motion in seconds. The retractable legs yield more than 7 inches of leveling adjustment, so you can have a stable ladder, regardless of the terrain.
The Quantum is compatible with select accessories offered by Little Giant Ladder Systems®, like the AirDeck® workstation and the Quantum Step™.
Meeting or exceeding all OSHA and ANSI standards, the Quantum is a Type IA ladder rated to hold 300 lbs.

What’s the difference between model size and extension height?
You may have noticed that our model sizing is taller than the actual extension height of any telescoping Little Giant ladder. This is due to the requirements of US ladder standards, published by the American National Standards Institute (ANSI): A14.2 for aluminum ladders and A14.5 for fiberglass ladders. These standards dictate that ladder model size should be displayed as the total rail length of each section of a ladder. All US manufacturers use the same sizing system in order to comply with ANSI. Extension ladders, articulating ladders and other multipurpose ladders often have multiple sections, so the ANSI-compliant size is the sum of the lengths of each section, not the actual maximum extended height. Please refer to the individual ladder’s instruction manual for details on maximum working length, highest standing level and maximum reach. We’ve described a few of these measurements in detail below.
What is maximum working length?
The final locks on any telescoping ladder sections will adhere to ANSI requirements, meaning there will be an appropriately sized overlap between inner and outer railing when fully extended. The maximum working length is the length of the ladder at its final locked extension length.
What is highest standing level?
Depending on the ladder and configuration, ANSI standards dictate that certain rungs (such as the ladder top cap or top step of an A-frame ladder) should not be used as a step. The highest standing level takes those standards into consideration and measures the highest ANSI-approved standing rung when the ladder is extended to maximum working length.
What is maximum reach?
Maximum reach (or “max reach”) is the combination of the ladder’s highest standing level and a common user’s reach height. The reach height addition is based on a 5'6" [1.68 m] person with a 12" [30 cm] vertical reach. The term is used in ladder merchandising throughout the climbing solutions industry to help users quickly comprehend which projects are compatible with which ladders.
