Tie Down Safety’s Step-N-Safe Extension Ladder Walk-Thru Pro is designed to fit most ladder profiles in the market. Fully compatible with ladders from Type II to Special Duty Type IIA, The Step-N-Safe Pro version utilizes a dual clamping safety lock system which improves stability when accessing the handrails of the Walk-Thru. The system is a two-piece (with the bottom and top assembly separating,) allowing the worker to easily remove the arms after use to either store for safe keeping or reduce the extended length of the ladder. The Step-N-Safe Pro is designed with additional accessory use such as a convenient ladder standoff. Ideal for roof, painting, siding, and window work. The height of the Step-N-Safe Pro allows for easier compliance with the proper ladder elevation above the walking surface, which is 36″. The Step-N-Safe Pro also has a broad base with non-skid rubber padding that increases the work surface’s contact area while transitioning to an elevated walking surface. The non-skid rubber padding also protects against the damaging of gutters, etc. The Tie Down Safety Step-N-Safe is compliant OHSA 1910 and 1926.
