When the job demands extreme height without the bulk of scaffolding or a lift, the Little Giant Skyscraper (Model 10121) is the answer. This heavy-duty aluminum adjustable stepladder telescopes from 11 to 21 feet, giving you a maximum standing height of nearly 18 feet and an overall reach of up to 24 feet 5 inches — perfect for vaulted ceilings, high-bay warehouses, churches, arenas, and commercial facilities.

The Skyscraper is built around three key safety and usability features: U-Locks that allow quick, tool-free height adjustments along the full 11–21 ft range; sturdy palm buttons that shift the ladder between its compact storage position and working stepladder stance; and non-marring, non-slip snap-on feet that anchor the ladder firmly to the floor. Integrated safety straps add an extra layer of stability for both users on this two-person-capable design.

Assembled in the USA and rated ANSI Type IA (Extra Heavy Duty) at 300 lbs, the Skyscraper is compatible with a full range of Little Giant accessories — including the Work Platform, Project Tray, and Cargo Hold — to create a fully equipped elevated workstation wherever the job takes you. Backed by a 5-year warranty.
