The MicroBurst is the only stepladder with Fold-Flat™ technology. On the MicroBurst, the StableLock™ spreader system is the strongest part of the ladder, constructed of a high-strength steel alloy, creating a solid A-frame structure with no room for shifting or walking. The MicroBurst is 4 inches wider than most stepladders for increased lateral stability. Easy to store and carry, the MicroBurst stores at only 3 ½ inches wide, nearly half the space of a traditional A-frame stepladders.
