• a first sidewall and a second sidewall positioned in parallel and spaced relation to each other;
• a cross tie having opposed first and second ends, wherein the first sidewall is removably secured to the first end of the cross tie and the second sidewall is secured to the second end of the cross tie;
• and
• a spacer positioned between the first sidewall and the first end of the cross tie to define a space between the first sidewall and the cross tie, wherein the spacer is connected to the first sidewall and removably connected to the first end of the cross tie,
• wherein the spacer comprises a spacer body having a first side and a dowel portion projecting outwardly from the first side and received in a hole in the first sidewall, wherein the first side is wider than the dowel portion and abuts an inner surface of the first sidewall proximate the hole.
