The extrusions slide into the corner pieces and are fixed in place by flexible lugs (32,36) engaging with corresponding notches. Two opposite extrusions of the frame are telescopic, allowing the other non-telescopic extrusions to engage with the window frame by engaging with flexible projections attached to it. The non-telescopic extrusions are also equipped with the recesses to receive the rolled blind or mesh. The frame extrusions are made from aluminium ,and the corner pieces from injected plastics. <IMAGE></p> |
