38 can support at least u2153 of the weight of the box 12 as it is being lowered into place on first and second surfaces 40 in some embodiments the first and third portions 36 38 can support at least u00bd of the weight of box 12 as it is being lowered into place on first and second surfaces 40 in some embodiments the first and third portions 36 38 can support at least u2153 of the weight of the box 12 as it is being lowered into place on both the first and second surfaces 40 and the fourth and fifth surfaces 44 in some embodiments the first and third portions 36 38 can support at least u00bd of the weight of box 12 as it is being lowered into place on both the first and second surfaces 40 and the fourth and fifth surfaces 44 other ranges of weight support are also possible because the first and second portions 36 are relatively thick compared to both third portion 38 and the thin ledge comprising surface 42 and because first and second surfaces 40 are positioned near corners of the box 12 already on the ground the weight of other box 12 is easily supported by the two contact points or areas near the corners of the boxes 12 if the weight of the other box 12 were to be lowered onto the surface 42 the ledge comprising surface 42 may likely break or fracture similarly the third portion 38 may break or fracture thus providing relatively thick first and second portions 36 along with recessed receiving areas 40 near the corners of the box 12 can facilitate.
