a pair of parallel and spaced apart side rails locatable against respective sides of a window opening; a head assembly including a roller upon which is wound a screen, said head assembly extending between said side rails and adapted to be mounted on upper ends of said side rails to be supported thereon against or adjacent to an upper side of the window opening; wherein said head assembly comprises; an elongate hollow housing adapted to enclose said roller and a portion of said screen wound thereon; and a pair of end caps fitted on ends of said housing, with said roller and said portion of said screen extending between said end caps, said screen being arranged to extend through an elongate gap in a lower side of said housing; each of said end caps including a mount for supporting a respective end of said roller and an attachment assembly for attaching said head assembly to said side rails; and said attachment assembly of each of said end caps comprising a first part engageable with a second part provided at said upper end of each of said side rails; and wherein said first and second parts are adapted to couple together at a plurality of different vertical positions with respect to one another to allow the vertical position of each of said end caps to be adjusted on the respective side rail to facilitate levelling of said head assembly. ### Claim 10 (depends on 9) The screen assembly of claim 9, further comprising a foot at each of said upper ends and at lower ends of each of said side rails, wherein said feet are adapted to frictionally engage respective upper and lower faces of the window opening, at least one of said feet of each of said side rails being linearly extendable from a remainder of the respective side rail to adjust the length of said side rail. ### Claim 11 (depends on 10) The screen assembly of claim 10, wherein said upper foot at said upper end of each of said side rails is linearly extendable therefrom, and further comprising a drive for extending each of said upper feet from the respective upper ends of said side rails. ### Claim 12 (depends on 11) The screen assembly of claim 11, wherein said drive comprises a threaded rod adapted to be screwed out of a threaded base member of the respective side rail to extend one of said upper feet from the respective side rail. ### Claim 13 (depends on 12) The screen assembly of claim 12, wherein said threaded rod is provided with a formation for engagement by a tool to facilitate rotation of said threaded rod and extension of said one of said upper feet from the respective side rail. ### Claim 14 (depends on 9) The screen assembly of claim 9, wherein at least one of said end caps is telescopically fitted over a respective end of said housing and includes a biasing device for urging the respective end cap towards an extended position to adjust the width of said head assembly to allow for variation in the width of the window opening. ### Claim 15 (depends on 14) The screen assembly of claim 14, wherein locking members are insertable through receiving channels in said end caps of said head assembly to engage receiving apertures formed in said side rails to secure said head assembly to said side rails. ### Claim 16 (depends on 9) The screen assembly of claim 9, wherein said first part of each of said attachment assemblies comprises vertically spaced and substantially horizontally extending opposed channels extending parallel to an end surface of the respective end cap to define a vertically aligned and horizontally extending slot into which is slidingly received a pair of parallel legs extending substantially horizontally from said upper end of each of said side rails, said legs defining said second part of the respective attachment assembly. ### Claim 17 (depends on 16) The screen assembly of claim 16, wherein inner faces of said channels and cooperating outer faces of said legs are provided with cooperating serrated or tooth like formations adapted to engage one another as said legs are slid into said channels such that said end caps can be mounted on the respective side rails in a number of different vertically spaced positions. ### Claim 18 (depends on 17) The screen assembly of claim 17, wherein the relative vertical location and level of said head assembly with respect to the upper side of the window opening is adjustable within limits defined by a difference between the distance between upper and lower faces of said legs and the width of said slot that is defined by said channels within which said legs are received. ### Claim 19 (depends on 9) The screen assembly of claim 9, wherein said side rails define a pair of opposing substantially U-shaped guide tracks adapted to extend perpendicular to the respective sides of the window opening and within which a respective edge region of said screen is guided during raising and lowering of said screen. ### Claim 20 (depends on 19) The screen assembly of claim 19, wherein a guide bar is mounted on a lower end of said screen, said guide bar being adapted to slide within said guide tracks defined by said side rails.
