on the lower of the transverse strengthening bars 3 one knob 10 at each end a small stowable handle is suitably provided on the rear face of the screen for handling the screen from the outside this is suitably provided on the transverse bar 3 or on the leading edge stile 2 b and is particularly suitably pivotable to collapse substantially flat against the screen so that when the screen is fully drawn back against the static pane of the french windows the screen lies very closely against the static pane of the french windows such a pivotable handle 12 is illustrated in fig1 c to 1 e as comprising a ring 12 that is pivotally mounted to the horizontal strengthening bar 3 by a bearing 13 as also shown in fig1 c a spacer pad 14 is suitably provided at least adjacent to and suitably either side of the pivotal handle 12 primarily to counter risk of the stowed handle contacting the window but also spacing the cross bar 3 away from direct contact with the window in the preferred embodiment the pivotal handle is magnetic such as to be magnetically attracted back to its stowed position closely adjacent the screen by way of further detail apparent in the figures the screen is provided with triangular corner pieces at each corner of the frame to better hold the mesh of the screen in place within the frame turning to fig6 b this shows the fig1 c version of the screen as pulled to the doorway closing position here the closure rail 8 b on the door jamb 8 has a distinct channel defining shape to ensure that.
