All products in this range are designed for trade and professional use. Fiberglass is an incredibly strong material and therefore a Fiberglass Extension Ladder is very sturdy and durable. If it is durability you are looking for, a Fiberglass Extension Ladder is the perfect choice, as it is far longer lasting than an Aluminum Ladder. Fibreglass is non-conductive so is ideal for electricians and other tradesmen who are working with electrics or where there is a risk of electric shock. Our fibreglass ladders are manufactured to trade standard with the majority rated to EN131.
