  • Contractors and Water Authorities will have major benefits regarding OH&S issues particularly weight. At approx. 5Kg per meter the ladder is significantly lighter than steel or stainless steel.

The package

The modular ladder system was designed to provide a product that could be supplied off the shelf for next day delivery.

ADD-A-STEP® is manufactured from different types of engineering polymers. Each module of the ladder consists of two stiles, one rung and two retaining clips. Each stile measures 360mm long, 80mm wide and 32mm thick maximum dimension. The ladder width outside the stiles (uprights) is 435mm and it weighs approximately 5kg per lineal metre.

Perfect for use as sewer ladders, this product has 30mm diameter rungs 300mm centre spacing and the width or foot space inside the stiles is 375mm. The ladder is assembled on site using the number of modules required to achieve any length equipment.

Each ladder box measures 425mm long x 360mm wide x 190mm high and contains three metres of ladder and three bracket sets. Any number of modules can be purchased.

The ADD-A-STEP® system offers supply off the shelf for a next day delivery.
