A position adjustable support assembly provides a support extension that is detachably attachable to a support member. The support extension is attached by an extension attachment that has a support coupler that extends along the length of the support member and has a gap opening to allow the support coupler to be snapped onto the support member. The support coupler may be cylindrical in shape and snap over the rod-shaped support member in a concentric coupling arrangement. The support member has a fin slot for retaining a plurality of fins that extend up from the outside surface of the support member. The fins are slid into a retaining slot along the inside surface of the support coupler to retain the support coupler and support extension in a rotational position with respect to the support member. The support extension can be slid along the length of the support member.

A hook rail assembly for hanging objects on a wall includes an elongated rail member for abutting the wall, at least one anchor component connected to a back side of the rail member and at least one hook member positioned at a front side of the rail member. The anchor component including a base and at least one wall penetrating retainer, the wall penetrating retainer having a wall penetrating extent that that protrudes rearwardly of the rail member and has a curved configuration. The wall penetrating extent may be arcuate and have a radius of curvature with a center point proximate a bottom side of the rail member.

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 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.
