Manthorpe MAGL250/03 Drop Down Loft Access Door

The GL250-03 Drop Down Loft Access Door provides an unobtrusive and cost effective alternative to traditional loft space access. The door has a twist action, three point closing mechanism along with a unique hinge system, allowing the door to be hinged down or be removed from the frame completely for unobstructed access into the roof space.

Draught seals are located to seal between both the frame and the ceiling and the door and the frame. These prevent the problem of moist warm air entering the roof space and meet the air leakage requirements of Part L of the building regulations. The product is also supplied with 50mm of expanded polystrene insulation to thermally insulate the back of the door.

The door and frame is stylish yet unobtrusive which has been designed to fit in with almost all house décor styles. With a lightly textured white finish the door can be easily cleaned with a solvent free damp cloth, or alternatively the GL250-03 can be painted to match the décor.

The door catch can be operated by hand or with a pole by using the pole attachment located in the insulation on the back of the door (pole not supplied). The door can also be used with the GLL256 and GLL257 loft ladders, the catch can be easily operated with the loft ladder pole.
