The Little Giant LT multi-use ladder system is constructed of a special alloy that makes it nearly 20% lighter than any comparable industrial-rated ladder. The LT also includes several innovative new features such as the dual-pin hinge and the easy-to-use Rock Locks for quick adjustment. The LT can be used as an A-frame, extension, and staircase and 90-degree ladder. It can also be used with Trestle Brackets (sold separately) to form a trestle-and-plank scaffolding system. The LT''s wide-flared legs and aerospace-grade aluminum construction provide an unmatched feeling of safety and stability. The Little Giant LT is rated to hold 300 pounds on both sides and is a true two-person ladder.
