Perfect for properties with shared accommodation, Manthorpe's lockable GL251 drop-down door for loft access is ideal for preventing unauthorised persons getting into the loft space. Complete with the unobtrusive, sleek design for which the door is favoured, this product is supplied complete with a key lock and three-point mechanism for boosted security. The insulated area at the back of the door is fully maximised (available in 0.35 and 0.15 W/m²K options) and the seals are supported by a number of perimeter catches. The lockable sliding mechanism is operated from one point for ease, and the hinge pivot is carefully positioned to ensure the largest possible opening. Designed with secure catches to deliver effective draught sealing and prevention against wind uplift, this innovative drop-down door design comes with a pre-formed frame and is supplied with appropriate fixing screws. A textured finish allows for easy cleaning over time.
