A customizable closet organization system includes support elements that can be selectively combined and arranged. A closet organization system includes a support track, a support rail, and a shelf support bracket. The support track includes apertures for mounting the support track horizontally to a wall. The support rail includes bracket mounting slots and is configured to hang from the support track so that the bracket mounting slots face the wall. The shelf support bracket includes a support arm and a mounting hook. The mounting hook is configured for insertion into one of the bracket mounting slots to secure the shelf support bracket to the support rail so that the support arm extends transversely from the support rail and away from the wall in a mounted configuration of the shelf support bracket.

A connection piece of columns of a goods rack, where the connection piece includes a connection body, the connection body has a bending structure matching the column, and anti-misplacement horizontal support plates facing toward a bending inner side and protruding along a direction perpendicular to the connection body are in a middle part of the connection body. A first column connection hole is at a lower part and an upper part of two bending sides of the connection body respectively. A second column connection hole matching the corresponding first column connection hole is on two bending sides of the column respectively. After both ends of the connection body are cooperated with two columns, ends of the two columns are respectively abutted against corresponding end faces of the corresponding anti-misplacement horizontal support plates. An expansion buckle is in the matching first column connection hole and second column connection hole.

An article transport facility includes support columns (2) and support beams (5) that are coupled to the support columns (2) and support rails (7). The support beams (5) each include a beam body (50), attachment members (55) for attachment to the support columns (2), and support members (60) that are fixed to the beam body (50) and are for supporting the rails (7). A support beam (5) and a support column (2) are coupled together by locking portions (59) provided on the attachment members (55) being locked to lock receiving portions (21) formed in the support column 2, and by binding with use of first binding members (B1) inserted through first through holes (66) formed in the support members (60).

A closet organization system includes a closet rod support member configured for mounting to a wire shelf. The closet rod support member is configured for supporting a closet rod and includes an attachment feature with a first slot and a second slot. The first slot is oriented for engagement with a first support rod of the wire shelf via movement of the closet rod support member in a first direction relative to the first support rod. The second slot is oriented for engagement with a second support rod of the wire shelf via movement of the closet rod support member in a second direction relative to the first support rod. The second direction is transverse to the first direction. The second slot is configured for engagement with the second support rod while the first slot is mounted to the first support rod.
