ABSTRACT:
A kit of parts for constructing a loft hatch frame comprises four extruded `T`-section mouldings 12 and four corner plates 14. Each moulding 12 comprises an elongate face plate 12a and an upstanding longitudinal web 12b upstanding generally centrally from the face plate. In use the mouldings 12 are cut slightly shorter than the sides of the loft access opening, and nailed to the ceiling purlins through the upstanding webs 12b. The face plates 12a closely abut the ceiling and together provide an internal shoulder on which an access panel rests. Each of the four corner plates 14 has a pair of recesses 16 formed therein, shaped to receive the ends of the face plates 12a of a pair of the extruded mouldings 12. Thus the corner plates 14 mask the junction between adjacent mouldings 12, and provide a neat finish even though the mouldings have not been cut to exact length.
