PROBLEM TO BE SOLVED: To provide a fixed face-centered lattice and an escaped face-centered lattice capable of sufficiently ensuring a crime prevention function by the face-centered lattice, preventing the operation of removal of the face-centered lattice from the outside and unlocking of a locking means so that a hand can not be put in a gap between vertical sash bars by closing the gap between the vertical sash bars arranged at a regular interval. SOLUTION: In the face-centered lattice assembling a lattice body 24 by arranging a large number of vertical sash bars 23 between up and down horizontal sash bars at regular intervals, the vertical sash bar 23 is formed by combining fixed sash bars to the horizontal sash bars with a required number of movable sash bars capable of being pulled out from a state stored in the fixed sash bars to one side in the direction of arrangement of the vertical sash bars, and each movable sash bar is so interlocked that a state stored in the fixed sash bar can be combined with a state pulled out from the fixed sash bar.
