Each of the beams has a main body, an extension extending from a first end of the main body and a second extension extending from a second end of the main body. The first end of the third and fourth beams have an opening defined therein and a slot sized to receive either the first extension of the first beam or the second extension of the first beam. The second end of the third and fourth beams have a slot sized to receive the other of the first extension of the second beam or the second extension of the second beam. The first extension of the first beam is slidably positioned within the slot on the first end of the third beam and the second extension of the first beam is slidably positioned within the slot on the first end of the fourth beam. The first extension of the second beam is slidably positioned within the slot on the second end of the third beam and the second extension of the second beam is slidably positioned within the slot on the second end of the fourth beam and the posts of the third and fourth beams extend through the openings on the extensions of the second beam. |
