The vast majority of ladder accidents are caused by two things: using the wrong ladder for the job and overreaching. Little Giant Ladders designed the Little Giant Ladders IAA Model Multi-Use Ladder to help you avoid these common problems. The Dark Horse is the only fiberglass multi-use ladder on the market. Its wide-flared base provides much more lateral stability than straight-sided step or extension ladders, preventing many accidents caused by overreaching. And, because it is constructed with super-lightweight, super-strong fiberglass composite, the Dark Horse is a versatile tool for any jobsite. You can use the Little Giant Dark Horse Model 13 in 16 unique configurations, including A-frame, extension and 90-degree ladders. The Little Giant Ladders IAA Model Multi-Use Ladder literally replaces several sizes of stepladders and extension ladders, and unlike any other ladder, allows you to work safely on stairs.
