The Supreme Vertical aluminium loft ladder is specially developed for vertical installation. The retractable ladder is manufactured from high strength die-cast aluminium alloy components contained within, and attached to, a wooden hatch box and insulated trapdoor. The heavy duty spring mechanism allows you to raise and lower the ladder with a minimum of effort, with gas-struts providing additional dampening. As the door is opened, the spring assisted ladder gently unfolds onto the floor below. Large steps and pre-assembled telescopic handrail offer comfort, safety and ease of egress.

Case Studies

Heavy-duty vertical wall access loft ladder from Premier Loft Ladders. Installed by Artisan Loft Ladders

Vertical wall access hatch and ladder

The owners of a modern home had no means of access to the loft space in their property. They needed a loft ladder with a vertical wall access hatch, such that they could make use of this otherwise wasted space. Also, it was important that the ladder was of particularly high-quality and would last a long-time. The Supreme Vertical offered the perfect solution.

“Customers are always delighted and amazed at how a ladder of this size and weight is so light and easy to use.”

Steve, Artisan Loft Ladders
