A plurality of latch structures are coupled with the I-beam, each latch structure including a latch, and each end housing having a latch receiver, each latch in combination with a latch receiver allowing one of the latch structures to be releasably fixedly coupled with an end housing. In implementations a plurality of latch structures are coupled with the I-beam, each latch structure having a latch structure enclosure and each latch structure enclosure at least partially enclosing one of the end housings.
