Abstract:
1. A shelf for an electrical enclosure, the electrical enclosure including a four-post rack, the shelf comprising: a first shelf section including a first top planar surface, a front wall, a first side wall, a second side wall, a first bottom wall extending inward from the first side wall toward the second side wall, and a second bottom wall extending inward from the second side wall toward the first side wall, the first bottom wall including a first bent tab, and the second bottom wall including a second bent tab, the front wall including a first end and a second end, the first end and the second end each including a mounting tab that clips onto a post of the four-post rack and a mounting hole adapted to receive an expandable fastener in order to attach the first shelf section to the four-post rack without using any tools; a second shelf section including a second top planar surface, a third side wall, and fourth side wall, the third side wall including a first stop portion to engage the first bent tab and the fourth side wall including a second stop portion to engage the second bent tab in order to define a full extension position of the first shelf section with respect to the second shelf section; the second shelf section slidingly engaging the first shelf section such that the first shelf section and the second shelf section are configured to form a shelf surface having a usable shelf surface area that is variable; and a wiring hole positioned through the second top planar surface, the second top planar surface being longer than the first top planar surface in order to prevent the first top planar surface from covering any portion of the wiring hole so that wires can be routed through the shelf within the electrical enclosure.
