No other ladder compares - One Ladder Does it All . The Little Giant Ladder System is four to five times more durable than ordinary ladders. The Little Giant is made of heavy-wall 6005-T5 aluminum. And while it possesses a workload rated capacity of 300 pounds, it has been tested to withstand four times that amount without structural failure. Little Giant Ladders are versatile. The Model Twenty-Two replaces five different size "A" frames ladders, nine different size extension ladders, two scaffolding trestles with five heights, ten staircase ladders (for working on uneven surfaces) and four 90 degree ladders (for getting closer to walls and etc.). In fact, it would take nearly $800 in ordinary ladders to replace the capabilities of the Model Twenty-Two Little Giant. Even then, you would still lack the versatility, durability, and storage benefits of the Little Giant. The Type 1A is available in Models Thirteen, Seventeen, Twenty-Two and Twenty-Six. This unit includes a free work platform, a $39 value.
