With a work platform that extends beyond the base, these rolling ladders—also known as cantilever ladders—provide access to hard-to-reach areas, such as the top of large tanks and over conveyors. Wheel brakes keep these ladders stationary while in use. The number of steps listed includes the platform. Shipped assembled, except the handrails and base require assembly.

Counterbalanced-base ladders use a counterweight to stay stable, so their base isn’t as long as an extended base. As a result, it’s easier to position these ladders over tanks and other equipment where there isn’t room to slide the base underneath. Place the counterweight near the first step before use. Conversion kits turn counterbalanced-base ladders into extended-base ladders, eliminating the need for a counterweight. Without a counterweight, these ladders are easier to move.

Extended-base ladders don’t have a counterweight, so they’re easier to push around than counterbalanced-base ladders. Their base is longer than a counterbalanced base—but it’s only 8 1/4" high, so it can be rolled underneath conveyors and other machinery. Add a counterweight to turn these ladders into counterbalanced-base ladders. With a counterweight in place, you can remove the front base extension and install the front casters on the base section under the stairs.

Adjustable-height ladders can be raised or lowered within a 4 ft. range to give you the right height for each job. Use the included leveling jack foot to keep these ladders level on uneven surfaces.

For regular indoor use, choose a perforated tread. It has raised holes to keep you from slipping. For dirty jobsites, choose a serrated tread so debris falls through the steps. It has a sharp, raised surface for the highest level of slip resistance. The surface also scrapes mud from your work boots as you climb. Without boots, you may be uncomfortable standing for long periods.

Note: All ladders meet OSHA and Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
