Werner Aluminum LeanSafe X3 Ladder

It wasn’t too long ago that we had the pleasure of safely climbing around on the corner-friendly and easy-to-use Werner LeanSafe fiberglass ladder. We’ve also learned recently that Werner has extended the LeanSafe line into other areas, including their X3 line and this aluminum ladder. It still provides the feature set that makes it so safe and easy to use, but now it comes in a lightweight and rugged aluminum frame.

Non-conventional stepladders continue to gain traction in the industry because of their focus on ladder versatility and convenience. The Aluminum LeanSafe X3 is incredibly easy to use, aids in productivity, and helps worksites stay safe and compliant in a wide range of use cases. It’s a product that will help pros accomplish more at a great value!

What’s the Big Deal?

Really, the big deal surrounding the Werner Aluminum LeanSafe Ladder is that it features an aluminum frame, as opposed to the fiberglass frame of the previous edition. While this doesn’t give you the shock resistance of the fiberglass, the aluminum offers similar strength and durability but with even less weight. In this case, it weighs just 22.8 lbs. compared to the 24 pounds of the original LeanSafe X3 ladder.

Of course, the Werner LeanSafe Series also has a lot going for it whether you opt for the aluminum or for the fiberglass. The 3-in-1 design lets you deploy it as a step ladder, straight ladder, or leaning ladder. It features a one-handed adjustment that lets you swap positions seamlessly.

The Werner Aluminum LeanSafe ladder can also be used against corners, studs, poles, and other vertical surfaces. It has non-marring rubber feet and leaning pads to make sure you don’t scratch up any of your work surfaces. It even comes with a magnetic tool tray and paint hook to keep your important materials secure.
