An air conditioning unit or a heating unit can be installed in the security sleeve through the first end.

What is claimed is: 
     
         1 . A security sleeve comprising:
 a top panel;   a bottom panel;   two side panels;   a first end and a second end;   wherein the first end is open and the second end is at least partially closed by at least one bar;   wherein the at least one bar is secured to the second end.   
     
     
         2 . The security sleeve of  claim 1  wherein the security sleeve is sized to fit into an opening in a wall. 
     
     
         3 . The security sleeve of  claim 2  wherein the opening is in a shipping container. 
     
     
         4 . The security sleeve of  claim 2  wherein the security sleeve is secured to the wall. 
     
     
         5 . The security sleeve of  claim 1  wherein the at least one bar includes at least four bars spaced along the second end. 
     
     
         6 . The security sleeve of  claim 1  wherein the security sleeve is sized to receive an air conditioning unit or a heating unit through the first end. 
     
     
         7 . The security sleeve of  claim 6  wherein at least one drain hole is disposed adjacent the second end. 
     
     
         8 . The security sleeve of  claim 6  wherein the air conditioning unit or the heating unit is secured to the security sleeve. 
     
     
         9 . The security sleeve of  claim 1  wherein the security sleeve and the at least one bar are formed of metal. 
     
     
         10 . A method of using a security sleeve comprising:
 forming the security sleeve; wherein the security sleeve includes a top panel, a bottom panel, two side panels, a first end, and a second end; wherein the first end of the security sleeve is open and the second end is at least partially closed by at least one bar; wherein the at least one bar is secured to the second end;   installing the security sleeve in an opening of a wall.   
     
     
         11 . The method of  claim 10  wherein the opening is in a shipping container. 
     
     
         12 . The method of  claim 10  wherein the security sleeve is secured to the wall. 
     
     
         13 . The method of  claim 10  wherein the at least one bar includes at least four bars spaced along the second end. 
     
     
         14 . The method of  claim 10  wherein the security sleeve is sized to receive an air conditioning unit or a heating unit through the first end. 
     
     
         15 . The method of  claim 14  wherein at least one drain hole is disposed adjacent the second end. 
     
     
         16 . The method of  claim 14  wherein the air conditioning unit or the heating unit is secured to the security sleeve. 
     
     
         17 . The method of  claim 10  wherein the security sleeve and the at least one bar are formed of metal.
