M-Dividers have two or three brackets, depending on the height ordered, which attach to rear beams and extend the M-dividers outward toward the front of the bay. The front edges are rounded and leave no sharp edges extending into the aisles for added retail safety. Orders can be placed for M-dividers that will accommodate bays of any depth. It should be noted that measurements when ordering M-dividers should begin from the face of the bracket, and sizes should be ordered with a depth less than the upright so that the M-dividers do not protrude into the aisle. For example, if the upright depth is 42″, the most common practice would be to use a 36″ M-divider.
