Described is a fastener that includes a shank having a thread, a head, and a stepped portion situated between the head and the threaded portion. The stepped portion has a diameter that is larger than the diameter of a round hole in a first type of mounting rail and smaller than a length of a side of a square hole in a second type of mounting rail. When the fastener is inserted into a round hole, the stepped portion is urged against a front surface of the mounting rail. When the fastener is inserted into a square hole, the stepped portion enters closely into the square hole and the head portion is urged against the mounting rail. Accordingly, the fastener can be used with either of two types of mounting rails: Universal Mounting Rails and EIA Standard Mounting Rails.

Described is an adjustable side rail having a first elongate rail portion, a second elongate rail portion, and a tab projecting from one end of one of the first and second elongate rail portions. The second elongate rail portion has spatially separated opposing upper and lower grooves. Each groove slidingly receives one of the top and bottom edges of the first elongate rail portion when the first elongate rail portion engages the second elongate rail portion. The tab has a side edge with a notch formed therein for catching an edge of a hole in a mounting rail into which the tab is inserted and for anchoring the one end of that elongate rail portion to the mounting rail while a length of the side rail is adjusted.

Described is a label cassette for mounting to the front side of an enclosure and for holding and displaying a label used to identify a configuration of that enclosure. The label cassette includes a transparent cover, a tray, and a hinge mechanism. The tray has a pair of guide rails for engaging respective guide structures on the enclosure to align the label cassette for attachment to the enclosure, a capture mechanism to secure the label cassette to the enclosure, and a label surface to hold a label. The hinge mechanism attaches the transparent cover to the tray and permits rotation about an axis parallel to the back edge of the transparent cover. Mounted to a ledge that extends from the front of the enclosure, the label cassette does not occupy vertical space or interfere with connectors, cables, or airflow vents on the front of the enclosure.

Described is a bezel for an electronics enclosure. The bezel frame includes a frame, first and second plunger mechanisms, a shuttle, and a locking mechanism. The locking mechanism has a cam disposed in a path of lateral movement of the first plunger mechanism. The cam is located between that plunger mechanism and a tab of the shuttle. The orientation of the cam determines the extent of lateral movement of the plunger mechanisms. In one orientation, the cam restricts the lateral movement of the first plunger mechanism and urges the shuttle into a position that restricts the lateral movement of the second plunger mechanism. Consequently, neither plunger mechanism is able to move far enough laterally to disengage from a mounting structure.
