At least one embodiment of the inventive technology may be a support apparatus that includes at least two item support rails supported by support legs coupled thereto by pivot coupler apparatus that enable rotatable motion of a coupled support rail about a substantially vertical axis, where at least one of the item support rails is a non-horizontal item support rail, and where a cable passes through at least a portion of one or more of the support rails. In certain embodiments, the couplers may be height adjust couplers that enable substantially purely vertical, translatory height adjustment of coupled support rails and/or the couplers may couple item support rails to rail support legs at an angle other than ninety degrees. Items that may be supported include but are not limited to electronic percussion instruments.
