We have designed the Little Giant MightyLite(TM) to address the three leading types of stepladder injuries: Painful shoulder, neck, and back injuries from carrying heavy equipment Dangerous falls from standing on the top step or top cap Ankle, knee, and back injuries from missing the bottom step while descending the ladder First, the MightyLite is significantly lighter than any comparable traditional stepladder. Second, the MightyLite's platform design helps to prevent users from standing on the top step or top cap, the most common cause of severe stepladder falls. Third, the MightyLite's patented-pending Ground Cue prevents injuries by signaling the user when it is safe to dismount the ladder. The MightyLite's no-pinch platform design opens easily from a slim 5" storage profile and offers wide, comfortable treads on each step, with a spacious, comfortable standing deck. Its innovative top cap allows to you keep everything you need close at hand-no more trips up and down the ladder for tools or hardware. The Little Giant MightyLite is available in both Type IA 300 lbs and Type IAA 375 lbs ratings.
