         7 . (canceled) 
     
     
         8 . An apparatus according to  claim 1 , further comprising:
 a second stop coupled to the first side of first support to engage the first side of the second support adjacent to a central portion of the second edge of the second support in a case that the first latch engages the first opening of the second support; and   a third stop coupled to the first side of first support to engage the first side of the second support adjacent to a first end of the second edge of the second support in a case that the first latch engages the first opening of the second support,   wherein the first stop is to engage the first side of the second support adjacent to a second end of the second edge of the second support in a case that the first latch engages the first opening of the second support.   
     
     
         9 . (canceled) 
     
     
         10 . An apparatus according to  claim 1 , wherein the second support defines a second opening disposed adjacent to the second edge of the second support, the apparatus further comprising:
 a second latch integral with the first support, to engage the second opening of the second support, and comprising a second projection to pass through the second opening, the second projection to engage a second side of the second support in a case that the second latch engages the second opening of the second support; and   a second stop coupled to the first side of first support to engage the first side of the second support in a case that the second latch engages the second opening of the second support.   
     
     
         11 . An apparatus according to  claim 10 ,
 wherein the first latch and the second latch are disposed between the first stop and the second stop.   
     
     
         12 . (canceled) 
     
     
         13 . An apparatus according to  claim 1 , wherein the first opening is defined by at least one beveled portion of the second support. 
     
     
         14 . (canceled) 
     
     
         15 . (canceled) 
     
     
         16 . An apparatus according to  claim 1 , wherein the second support comprises:
 a third beveled edge and a fourth beveled edge opposite the third beveled edge,   a first bevel extending from the third beveled edge toward a central portion of the second side of the second support; and   a second bevel extending from the fourth beveled edge toward the central portion of the second side of the second support.   
     
     
         17 . An apparatus according to  claim 1 , wherein the second support is denser than the first support. 
     
     
         18 . An apparatus according to  claim 1 , wherein the first support comprises anti-skew ribs.
