Model #: 19313
The Adjustable Fortress™ is the safest and most convenient elevated platform on the market. It’s built to keep you moving, protected, and in control. With 360-degree all-around protection, the enclosed platform, wraparound rails, and auto-closing gate keep you secure from every angle, giving you full freedom without compromise.
Patented Rapid Locks let you adjust rail height in seconds, so one ladder handles multiple tasks without slowing you down. Extra width and depth give you room to move, even fully geared up, while the oversized platform, toe-kick protection, and independent leg leveling deliver unshakable stability on gravel, slopes, or uneven ground. Wide-flared outriggers expand the base up to 3X to reduce side-tip risk, and the patented Ground Cue signals when you’ve reached the bottom step, cutting down missteps and rolled ankles.
Transport is effortless with Tip & Glide wheels and the Locking Wheel Lift Kit. Roll fully loaded, lift or lock when you’re in place, and stay focused on the job. The Adjustable Fortress™ sets up fast with one smooth motion and folds flat for compact storage when the work is done. A built-in tray keep your tools ready for action, while our signature Hi-Viz Green fiberglass keeps you visible and protected from start to finish.
Type IAA rated to 375 lbs, the Adjustable Fortress™ delivers all-in durability, jobsite-tested toughness, and pro-grade performance without compromise.

Size refers to the ANSI definition of length. ANSI states that the size is defined by the combined length of all rail sections, with a tolerance of +/-3” on each section. Note, this does not take into account any overlap between sliding sections like those on an extension or multi-purpose ladder. This can cause a disparity in the size of the ladder versus the actual height. To determine which ladder you need, Little Giant recommends you reference maximum reach height instead of size.
The terminology for ladder duty ratings, grades, and types can sometimes be confusing. The ladder's duty rating is the maximum safe load capacity of that ladder according to ANSI standards. There are 3 types of ratings that Little Giant offers:
Type I - Made to handle everyday projects. Has a load capacity of 250 lbs.
Type IA- Designed with durability and regular use in mind. Has a load capacity of 300 lbs.
Type IAA- Built for professional performance and rugged use. Has a load capacity of 375 lbs.
Ladder specifications can be confusing due to safety regulation requirements. According to ANSI (American National Standards Institute), the ladder size is defined as the total length of each section and does not account for overlap on extension ladders. As a result, the overlapping sections reduce the total length of the ladder. When purchasing any ladder customers should pay particular attention to the maximum reach to ensure the correct product for the job.
