A shelf having two telescoping plates secured by a toothed crank is provided for locker users. The carrier stage has a carrier carrying a sealing element with a relatively larger orifice opposing a relatively smaller orifice. The plate is anchored to one vertebra by a first anchor, and a second anchor is then placed through the slot with the sloped internal edge or surface and tightened. An LED controller regulates the state of the LEDs by controlling whether each LED is on or off and adjusting the intensity of each LED in an on position.
