The system also includes a cover including a main body with a first end and a second end, and first and second hinge portions coupled to the first and second ends of the main body. Each of the first and second hinge portions includes a first member that extends to an end positioned to contact an inner surface of the first sidewall, a second member that defines an arm that is positioned to at least partially contact the first sidewall, and an extension member that extends from the second member in a direction opposite to that of the arm. The first and second members have a space therebetween sized to receive a portion of the first sidewall.
