Retro recessed electrical wall box

An electrical fixture box for installation in a hollow wall wherein said wall has an open cavity located between an inner-wall and an outer-wall in which an aperture is cut into the outer wall to allow for installation of said electrical fixture box, said electrical fixture box comprising:

• a closed bottom having at least one side wall that defines an interior space that is accessible through an open top;
• a leg section attachment screw centrally located on the closed bottom of the fixture box wherein a head of the leg section attachment screw is freely rotatable in relation to the closed bottom;
• said leg section attachment screw being accessible through the open top of the fixture box to allow the screw to be freely rotated in relation to the closed bottom;
• a leg section being attached to the closed bottom by the leg section attachment screw;
• said leg section being attached to the leg section attachment screw by a threaded connection;
• said leg section having at least one leg with teeth located thereon to allow the leg section to grip the inner wall and prevent the leg section from rotating while the leg section attachment screw is being rotated;
• and
• a plurality of folding side anchors extending from the at least one side wall wherein said plurality of folding side anchors are capable of pushing against the outer wall as the leg section pushes against the inner wall, thereby sandwiching the electrical fixture box within the hollow wall between the inner wall and outer wall.
