Featuring an innovative design, our Extension Ladders offer a higher reach than your standard conventional ladder. Doing exactly what the name implies, they extend to provide entry to areas that stepladders cannot. This benefit increases a user’s functionality by allowing a worker to safely access heights.

Our Extension Ladders are versatile, strong and stable. Their durable frames support working capacities of 130 kg to 150 kg. Combing a range of safety features in each design, these ladders are perfect for heavy trade, commercial and trades-person use.  These ladders are typically adopted in building and construction zones.

Available in either an aluminium or fibreglass construction, they are designed to suit a variety of applications and have industrial duty ratings.We also have Triple Extension Ladders and Extensions Ladders with Levellers available as well to suit varying applications.
