Bringing Ladder Safety Over the Top
Walk through your ladder, not around it. Complies with OSHA’S 36" extension rule for portable ladders. OSHA & WT02 Compliance Letter
The most awkward and dangerous maneuver of using any extension ladder is entering and exiting at the top. It’s an accident just waiting to happen…so be it any wonder that 80% of all falls from ladders happens at the top? Solving this safety issue was at the heart of our walk through concept.
Designed to attach over the top of the ladder, the Ladder Innovations Walk Through by AIC requires no tools, drilling or bolting to hold it securely in place. The Walk Through is designed with an off setting right, left flair that allows for safer enter on and off the top of the ladder even if you’re wearing a loaded up tool belt. In our opinion, adding the Walk Through to your ladders is one of the strongest statements regarding safety in the workplace you can make.

WT02 or WT04- unit price $325.00
