Retractable Roof Access Ladder and Hatch

Premier Loft Ladders were contacted by a specialist food processing plant to replace a damaged retractable roof access ladder. As this presented the only means of access for maintenance of roof top equipment, it was important that the replacement access ladder was strong, durable and easy to operate. Furthermore, a new weather resistant roof hatch was needed. The Supreme with flat roof access hatch provided the perfect solution.
