Little Giant Adjustable Ladder System  -  LiteWave™ Technology For starters, the RevolutionXE is lighter–20% lighter than any competing multi-use ladder on the market. We did this without sacrificing any strength thanks to patented LiteWave™ technology (the same technology used by the U.S. military in aircraft production). LiteWave™ technology allows for the convenience of a 250 lb. rated ladder, yet still provides the strength of a 300 lb. rated ladder.Get your Little Giant RevolutionXE ladder today, the lightest and last ladder you will ever need
