A mounting track system for mounting equipment at various locations along a length of a mounting track, the mounting track system comprising a mounting track and a mounting bracket, the mounting bracket comprising: a mounting plate with an outer surface facing away from the wall to which it is mounted and an inner surface facing toward the wall to which it is mounted; a plurality of mounting projections which include a stem and an enlarged head portion provided at the inner surface; and a locking projection provided at the inner surface, the locking projection capable of being biased toward an extended, lock position; the mounting track comprising: a first vertical plurality of securement slots, wherein each securement slot comprises an enlarged open region adjacent a necked-down region, such that the enlarged head of a mounting projection of the mounting bracket may pass through the enlarged open region to allow the stem connected to the enlarged head to slide down the necked-down region such that the enlarged head cannot be removed through the necked-down region; a second vertical plurality of securement slots in parallel with the first vertical plurality of securement slots, where each of the second vertical plurality of securement slots are horizontally aligned with the first vertical plurality of securement slots such that the first vertical plurality of securement slots and the second vertical plurality of securement slots can simultaneously receive a pair of horizontally aligned mounting projections of the mounting bracket, wherein each securement slot comprises an enlarged open region adjacent a necked-down region, such that an enlarged head of a mounting projection of the mounting bracket may pass through the enlarged open region to allow the stem connected to the enlarged head to slide down the necked-down region such that the enlarged head cannot be removed through the necked-down region; and a vertical plurality of openings, the vertical plurality of openings operable to receive a locking projection of the mounting bracket thereby preventing vertical movement of the mounting bracket when the stems of the horizontally aligned mounting projections are disposed in the necked-down regions of the first and second vertical plurality of securement slots (174, 178); wherein the necked-down regions continuously connect adjacent enlarged head portions within the first vertical plurality of securement slots and within the second vertical plurality of securement slots; characterized in that the vertical plurality of openings are disposed between the first vertical plurality of securement slots and the second vertical plurality of securement slots. a mounting plate with an outer surface facing away from the wall to which it is mounted and an inner surface facing toward the wall to which it is mounted;
