FIG. 2 is a top plan view of the security sash lock of the present invention, with the front and back components thereof disassembled;
FIG. 3 is a front elevation of the security sash lock of the present invention, as shown in FIG. 1; and,
FIG. 4 is a left side elevation of the security sash lock of the present invention.
