A solid loft ladder setting in the ceiling is essential for safety and comfort of use. For concrete ceilings, stable fastening is ensured by the LXF-C screw set, while the LXF-W set works well for wooden ceilings. The LXP wedges allow for precise positioning of the box in the opening, eliminating the risk of skew and unevenness. The LXK mounting brackets stabilise the corners and maintain perfect angles, significantly improving the durability of the entire structure. Combined, these elements form a solid foundation that retains its properties during use.
