Louisville 12 Ft Fiberglass Step Ladders

Louisville Ladder, Werner, and Little Giant are among the top-rated stepladder brands for professional use. All three manufacture fiberglass step ladders available with Level-EZE® automatic levelers as factory-installed options. For worksites involving uneven terrain, stairs, or slopes, adding an automatic leveler to any quality brand stepladder is strongly recommended for safety and efficiency.

A typical 12 ft fiberglass step ladder weighs between 30–40 lbs depending on the duty rating and model. Louisville Ladder's fiberglass step ladders in this range generally fall within this weight class. Installing Level-EZE® levelers adds only approximately 4–5 lbs, which is significantly lighter than manual leveler alternatives that typically weigh 8–11 lbs.

Level-EZE® mounts permanently to the base of the ladder legs. When you pick up the ladder, the levelers unlock automatically. When you set the ladder down on any surface — stairs, slopes, curbs, or rooftops — steel gears engage instantly, adjusting each leg independently in 3/16-inch increments up to 9.5 inches, locking securely with as little as 9 lbs of applied weight.

No. Level-EZE® is acknowledged by major manufacturers including Louisville Ladder and Werner as not voiding the ladder's original warranty when properly installed. Following the installation instructions — including the recommended bottom rung modification per Underwriters Laboratories guidance — ensures the ladder retains its original duty rating and manufactured length classification.

Level-EZE® automatically adjusts up to 9.5 inches to accommodate stairs, sloped driveways, rooftops, gravel, dirt, curbs, landscaping grades, and uneven concrete or pavement. Rubber pads provide traction across varied surfaces, and optional swivel feet are available for extreme terrain conditions, making it suitable for virtually any jobsite environment.

Installation takes approximately 25 minutes and can be completed as an owner install using the provided instructions and video guides available on YouTube. Alternatively, field installation is available through ladder and tool distributors for a small fee, and factory installation is offered directly by Louisville Ladder and other major manufacturers at the point of purchase.
