An electronics rack rail removably attachable to an electronics rack, the rack rail including at least one slide locking mechanism for removably securing the rail to the rack, the rail including a flat flange portion located at one end of the rail, the flat flange portion including a slot formed through the flat flange portion proximate to the end, the slide locking mechanism attached to the flat flange portion over the slot so that a portion of the slide mechanism extends through the slot, the slide lock mechanism comprising: a slide lock with a support base that has a top surface and a flat bottom surface, the bottom surface configured to slide along the flat flange portion of the rail, the base has a width that is wider than a width of the slot so that the base is supported by the flat flange portion; a release lever protrudes from the top surface of the support base and provides a structure or surface for a user's finger to slide the support base along the flat flange portion; a locking latch extends downward from the bottom surface of the base and through the slot in the rail, the locking latch includes a neck portion attached to the bottom surface of the base and a protruding tab attached to an opposite end of the neck portion, the tab includes a forward face with a portion that slopes away from the bottom of the base and toward a back of the slide lock, the tab includes a top surface extending forward from the neck and is generally horizontal or slopes away from the bottom surface of the base, the top surface of the tab is spaced apart from the bottom surface of the base a distance to accommodate the flat flange portion and a flange on the electronics rack; a body extends downward from the bottom surface of the base and is spaced rearward and apart from the locking latch, the body extends through the slot in the rail; and a spring mounted to or formed on the body and engages with the rail so as to bias the slide lock toward the end of the rail. a slide lock with a support base that has a top surface and a flat bottom surface, the bottom surface configured to slide along the flat flange portion of the rail, the base has a width that is wider than a width of the slot so that the base is supported by the flat flange portion; a release lever protrudes from the top surface of the support base and provides a structure or surface for a user's finger to slide the support base along the flat flange portion; a locking latch extends downward from the bottom surface of the base and through the slot in the rail, the locking latch includes a neck portion attached to the bottom surface of the base and a protruding tab attached to an opposite end of the neck portion, the tab includes a forward face with a portion that slopes away from the bottom of the base and toward a back of the slide lock, the tab includes a top surface extending forward from the neck and is generally horizontal or slopes away from the bottom surface of the base, the top surface of the tab is spaced apart from the bottom surface of the base a distance to accommodate the flat flange portion and a flange on the electronics rack; a body extends downward from the bottom surface of the base and is spaced rearward and apart from the locking latch, the body extends through the slot in the rail; and a spring mounted to or formed on the body and engages with the rail so as to bias the slide lock toward the end of the rail.
