SURFACE LATTICE

PROBLEM TO BE SOLVED: To provide a surface lattice superior in the prevention of crimes due to being difficult for opening-closing operation of a lattice body from the outdoor side, while easily performing maintenance of a sliding door paper sliding screen. SOLUTION: This surface lattice 1 is rotatably connected in an upper part to an upper part of a sash frame 9. A lower fixture 7 has a lattice body side bracket 15 fixed to a lower part of the lattice body 3, a sash frame side bracket 17 fixed to a lower part of the sash frame 9, a freely projecting/collapsible arm 19 arranged between both brackets, an operation knob 21 rotatably arranged on a lattice body side bracket, a through-hole 25 arranged in the sash frame side bracket 17, and a cover 23 openably-closably arranged on the lattice body side bracket 15. The through-hole 25 has a large diameter part 27 freely penetrating through the operation knob 21 and a small diameter part 29 freely locking the operation knob 21. The cover 23 shields the operation knob 21 locked on the through-hole 25 in a closed position, and is opposed to the sliding door paper sliding screen 11 of a full closure state arranged in the sash frame 9.
