Abstract: Modular enclosure includes a plurality of structural elements coupled to one another to at least partially define a cavity. The structural elements form a plurality of sub-assemblies in which each sub-assembly includes a corner section having a slot and first and second joint sections. Each of the first and second joint sections include an elongated body extending between two joint ends. The elongated body has an open-sided channel that extends along a length of the elongated body and opens to an exterior of the elongated body. The open-sided channel extends through each of the joint ends. The slot of the corner section is aligned with the open-sided channels of the first and second joint sections and a wall section is received by the slot and each of the open-sided channels.

Abstract: A hold down assembly for an electronic unit includes a locking washer having a cone at a front end thereof. The locking washer has a tang provided in the cone and extending forward from the cone. The cone is configured to receive a mounting hook of the electronic unit with a first side of the tang bearing against the mounting hook to lock the position of the locking washer relative to the mounting hook. An actuator knob is rotatably coupled to the locking washer. The actuator knob is configured to be tightened to a threaded shaft to tighten the hold down assembly to the electronic unit and drive the locking washer toward the mounting hook.
