Combination Ladders for Stairs | Level-EZE Auto-Leveling Stair Safety

Combination ladders are among the most versatile ladders for stair use because their adjustable configuration allows flexible positioning. When fitted with the Level-EZE® automatic leveler, aluminum or fiberglass combination ladders can be safely deployed on stairs, slopes, curbs, and rooftops — automatically compensating for surface height differences up to 9.5 inches.

A ladder with steps on both sides is called a stepladder or a combination ladder in its self-supporting mode. Combination ladders are multi-function tools that can be configured as a stepladder (with rungs on both sides) or as a single-sided extension ladder. Level-EZE® levelers are compatible with both configurations, including aluminum and fiberglass models.

When the ladder is placed on a surface, the Level-EZE® legs independently adjust via precision steel gears in 3/16-inch increments, compensating for height differences automatically. As soon as approximately 9 lbs of weight is applied, both legs lock simultaneously via an internal aluminum rod — securing the ladder in position in under one second with no operator input required.

No. The Level-EZE® is the only automatic leveler that meets all ANSI standards for portable extension ladders and has been tested by Underwriters Laboratories at 4x the ladder's load rating without failure. Most major manufacturers, including Werner, acknowledge that proper installation does not void the ladder manufacturer's warranty.

Owner installation takes approximately 25 minutes using the provided instructions and video guides available on YouTube. For those who prefer professional fitting, field installation is available through ladder and tool distributors for a small fee, and factory installation is offered directly by major ladder manufacturers including Werner, Louisville, and Bauer.

Maintenance is minimal. Occasionally apply dry silicone spray — such as WD-40 Specialist Silicone or Teflon lubricant — to keep gears moving freely. Avoid standard WD-40 or greases, which attract debris. In dusty environments, clean with pressurized water or air. In icy or snowy conditions, inspect and warm the unit before use to ensure proper operation.
